Looking for a replacement power relay

11 years ago

I have a GE Monogram dual-fuel oven. It's got a blown power relay, and I've come to find that GE no longer stocks that part, nor will GE provide any specifications for the part or any substitute. I've scoured the internet - I'm a pretty effective internet-scour-er, btw - and can't find the component for sale anywhere. Well, except for a guy on eBay who has apparently cornered that market and is asking 4x the price. Buying one from him would be my last-gasp, dying act (curse him).

I'm trying to identify a workable replacement. I've got everything figured out except for the coil (solenoid) amperage. The switched power is 240V, 5000W (21A). But the coil power... I do know that it's on the 120V side of the range. But I don't know what the coil amperage is.

I need to be able to pick the correct power relay which will be effectively operated by the existing coil circuit in the range. I'd rather not mess too much with modifying that circuit to adapt a different relay....


Here is what I think I can do:

  1. Plan A) calculate the amperage required to activate existing relay, based on its coil measurements
  2. Plan B) just order what I think will work (about a $20.00 part), and see if it will activate if I plug it into the circuit. Obviously, I'd leave the 220V unconnected for this little experiment.
  3. Plan C) turn the range back on, and stick an ammeter in the coil circuit and measure it. carefully.

Any other thoughts? Are there industry standards for these sorts of things? Looking at all the relays out there, they seem to typically use 1-5 amps.

    All,

    I'm working on finding the part number for the replacement part I mention above in my post. It's taking some time, since I've had a couple laptop changes since then, and I didn't keep some of the documentation that I downloaded back when I was resolving this issue.

    But here is what I have so far: First, my range is a ZDP48SS.... The relay that failed is the "hot wire relay" (abbreviated "HRW") on the ZDP48 wiring diagram and ZDP48 wiring schematic. The relay failed for the 30" oven, and the original GE part number is WB21X5362. On my version of the wiring diagram, this relay has points 40, 97, 89, 27/28, and 87. I have no idea whether this is the same part for the 12" oven, nor whether it is the same part on other models. I would surmise that any of the 30" ovens made during this era would have the same relay, but again, I don't know that for sure so please proceed at your own risk.

    Ok, now that I have that out of the way, I need to go find the alternate part number. I'll post here as soon as I find it, and then contact each person who asked, via direct message.

    Update: 6:43pm CDT: The pub no for the wiring diagram on my range is 31-20421. You can download this publication at http://appliancejunk.com/forums/index.php?action=dlattach;topic=16557.0;attach=9652.

    Yes, the Whirlpool part should be the same as the GE, if you end up finding it. I believe DCS used to make the JennAir pro ranges as well, so that's why they carried it.

  • 9 years ago

    Indytim640 I messaged you for the new part Thank you, denisonf@yahoo.com. Don't want to replace our Monagram. Thank you

  • 9 years ago

    anyone help me as I cant find the GE or WP or DCS part antwhere...Help

  • 8 years ago

    Could you please send me information on where to get the replacement part? I've had servicemen here for two days many hours telling me there's nothing they can do.

    Thank you!!!

    Has anyone found the part for the hot wire relay? I have a 48 in GE monogram oven and my broiler or clean won’t come on. Serviceman here for the second time. Already replaced the thermostat.

  • 8 years ago

    Indytim640 I’m in need of the same part. Please message me at greengablesgoodies@gmail.com

  • 8 years ago

    Sorry to hear you are having the same issue. Here is what I found.


    The GE part no is Hot Wire Relay, part number WB21X5362. It is no longer made, there are a few people selling them for ridiculous amounts on Ebay. The same Hot Wire Relay was used in many different ovens. I confirmed with our GE service Tech that the Thermador Oven 14-19-129 414589 Relay is the same Hot Wire Relay.


    The hot wire relay did'nt fix my issue, but maybe it will yours.


    Good luck

  • 8 years ago

    I also have a GE Monogram model ZDP48N6DD with the same problem. How can I make this Work? Can you direct me to the replacement relay? BTW I am Challenged with appliances so I would find a service company to install the relay.

  • 8 years ago

    Sorry, forgot to give my contact. I can be reached at stevemahana@gmail.com .. Thanks

  • 8 years ago

    The sanding down of the contacts worked for me, mine was in good shape, just worn contacts.

    Take this at your own risk as it will not be a true "plug and play" but if you have any electrical experience it may be worthwhile, as even the alternate part is very costly and hard to find.

    I found Whirlpool PN WP9752759 that I found searching for "Double line relay" is actually TE Part T92P7A22-120 (found from photos of the Whirlpool part) available at Arrow/Digikey/etc for around $15.

    I bought this as a backup but did not try it since sanding the contacts worked, but the specs are appropriate to allow it to work, except that the common side of the relay is 2 tabs instead of 1, so it would need a custom wiring harness to short those together. And its known use in appliances for the same application.

    An update on this issue. I'm sorry to see that so many folks have the same problem; I travel a lot and upon logging in, found over 20 messages asking for the alternative part numbers.

    I have to believe that someone with an Alibaba connection could get a couple hundred of these made -- seems like an opportunity to me.

    Above I posted that I'd be happy to share the alternative part numbers I've found. At this point, I cannot find any availability of those part numbers - it looks like they've all been bought up and are being profiteered on eBay.

    Currently, it looks like the Thermador part mentioned above by denisonf might be the only available replacement item, for less than $500. I have not looked at that part, myself, so I don't know if it's a direct match or not. Good luck.

    I installed a 40A 120v central air relay on my GE Monogram to replace the hotwire relay. It worked fine, except the switching signal from the thermostat fluctuates before it settles into 120v, which caused the AC "hard-closing" relay to click, clack and stutter whenever the thermostat sent the signal to the relay. It was so annoying I removed it and reinstalled the hotwire relay, which works on one of its two sets of point. I chose to have it operate the bottom element, as I use that more than broil.

    Anyone have thoughts about any soft closing or quiet relays for other devices out there that might work? I also wondered if a time-delay relay might work. Even if it had hard closing contactors/points, I'm thinking the the first fluttering voltage it sees from the thermostat might be enough to activate the timer (maybe one click). If set for a 10 or 15 second delay, then by the time 10 or 15 seconds elapses, the control voltage would have settled to 120v, firing the contactors in the relay (second click). I can live with a couple clicks, but as it was, the AC relay was clicking on and off loudly a dozen or so times before it settled down.

    Are there any updates about replacement hot wire relay for this GE 48
    " stove?

  • 8 years ago

    Hello, I am trying to burnish the contacts on the GE Hot Wire Relay, part #WB21X5362. I can find, remove and replace the relay. Would like detailed tips on contact access, how to burnish and what not to do. Thanks.

  • 8 years ago

    I'm a Bed & Breakfast owner that uses this GE Monogram 48" Duel Fuel Range for a living. I discovered that my Large oven wasn't working properly and a serviceman diagnosed that the Hot Wire Relay was bad, trying to find WB21X5362 is virtually impossible but we discovered that the little oven has the same Hot wire Relay!! So we switched them... My larger oven is working great! I'm still searching for the WB21X5362 to get the small oven working again. I wish we knew who manufactured these original parts!! I would buy a spare to have on hand. By the amount of people searching for this part, there is a need. If anyone has found a supply, please let me know. Stacy Helm, dshelm@zumatel.net

  • 7 years ago

    In my stove, the hot wire relay for the 30" oven was part number WB21X5362.

    I found that the Jenn-aire part number 73001324 also works - it's the exact same part.

    But even the Jenn-aire parts are getting hard to find - you might have to hunt around a bit.

    Good luck,

    Anyone have any updates on fing this hot wire relay or alternate parts that would work?

    there seems to be to relays one with a orange capacitor and one with blue,does anyone know if they are interchangeabl? Would appreciate any input thanks Mike, mikejschall@gmail.com

  • 7 years ago

    All, Just a quick note, the same hot wire relay was used in many different brands of stove. I found a Thermadore one that worked for me. These were also used in numerous other brands also. If you search around you should be able to find one for a reasonable cost. Sorry to hear your having problem too...

    The thermador hot wire relay is a direct replacement for the GE one. They made the same hotwire really for a number of different oven manufactures.

    Cleaning the contacts for the hot wire relay can’t hurt. My issue ended up being the wiring was burnt in the oven from self cleaning cycles. Had to replace the oven.

    Good luck

    I am now in need of this part as well. ( GE WB21X5362 ) if anyone has found a substitute, will you please email me at rdb5909@att.net. Thank you.

    @denisonf I wasn't able to message you directly, but if you still have the part and didn't end up needing it, would you be interested in selling it? PM me!

  • 5 years ago

    I need some help. I bought a replacement on eBay and it arrived today. I pulled the panel off but can’t seem to locate where it goes. The board is full and nothing resembles the relay.


    Please help me!

  • 5 years ago

    Suggest posting a bit more info: stove model, which panel, what you see, which oven (if the 48 inch GE profile. I think that hot wire relay has 240v direct connections to the power and the bake element. It is turning the power off and on to the oven elements. My schematics show it behind the lower front panel of the oven. So if you trace back from the wires that connect to bake elements, you should find the relay. Part # of relay? How does it look (new or used)? Also post if it works. GE really needs to make another run of these parts. Good luck

  • 5 years ago

    Mine was also behind the easily removable lower front panel. Make sure before you start working on this. Turn off the power breaker to the oven. A lot of very hot wires coming in or out of this relay or in the general area. I got mine from eBay over a year ago. What I did was to diagram all the wires coming into the relay took close up pictures and proceeded to replace the relay. Worked well. While at it I found some instructions on line to clean relays and with a nail file I cleaned the contacts in the other relay. Since this stove has two ovens seems like the relays are identical.

    GE a big disappointment.

    Thanks for the pics. PM me the name of the Ebay supplier if it works. I have same oven, and intermittent large burner oven. We only use it for Thanksgiving now. Very exciting and really hopes this works for you.


    Oh and good tip on the breaker Grafting. As an electrical engineer, its just something I assume everyone knows. 240 is dangerous.

    Could you tell me where it mounts though? Still confused.

    I suspect you have to do a custom mount; size looks different from original relay. Maybe a bracket in that open area to the right? Someone else on this thread what you are attempting, I think, and may have suggestions. More importantly, do know know the wire assignments? Getting past where I am comfortable offering advice, since I have not replaced the relay. Will try to post a schematic later today. Or search on the web.

    OP here.

    Since the small oven OEM relay was fine, I swapped it to the big oven. My small oven is now running on the bad relay, giving me the bottom element only.

    As stated above, an AC relay that costs just a few bucks works fine as a replacement for the GE OEM relay except for the issue described about a fluttering signal from the thermostat causing the hard closing "Click" of the AC relay to make an obnoxious clatter until the thermostat signal settles down after a few seconds.

    Got me to thinking if my OEM relays go out, I'd try an electronic relay with a delay/timer feature. If I'm right, the relay would be activated the moment the thermostat sends signal voltage and even if that signal flutters off and on, the relay won't actually close until the delay period I set (say, 10 seconds), is reached. By that time, the thermostat will have settled down and be sending a constant signal and all should be good. Just a thought.

  • 5 years ago

    Could you post a pic of where the relay mounts? At a dead end here.


    thanks so much!

  • 5 years ago

    OK, here are pics of my GE 48 inch oven schematics. The hot wire relay, marked "HWR 30"", is the big oven; HWR 12 is the small oven. If you note on the schematic, part of the relay might connect to the oven red LED that flashes on/off when the bake element is active. I think the HWR can be mounted (perhaps upside down?) anywhere the wires will reach. I count either 5 or 6 contacts and would love it if someone could describe the wire mapping from the GE Hot Wire Relay, WB21X5362 to the Thermador relay mentioned as a replacement. And earlier post mentions 6 connections to the GE relay.



    . Hope this helps.

    Thanks, my friend!

  • 5 years ago

    I don’t see anything in my unit that remotely resembles my new part.


    What am I missing?

  • 5 years ago

    I do not know. I am guessing you have the Thermador part from the pic you showed (numbers on other side: 14-19-129) The Thermador is, according to earlier comments on this thread, electrically equivalent, but perhaps in a different package? Perhaps call GE tech support and ask for a location. Or contact OP, Nick. I expected it to be easily visible too.

    I’ll let you know what I learn from him.

  • 5 years ago

    Don't see where you say what range model you have, but on the GE 48 Inch I have, the HW relays are side by side behind the blue terminal block you showed in your photo. The photo you show of the new relay is indeed what they look like.
