help with maytag microwave bulb

3 years ago

last modified: 3 years ago

Hello - Below is the picture of my old bulb (not confident if it is the correct one since we recently purchased condo) This bulb lights the interior of the microwave. When I called Maytag, and after holding on line for a good 20 minutes, all they could tell me was that the bulb should be incandescent 40W. They could not tell me about volts. Pictures below.

My question is how I can be sure that it is the correct bulb and if so, can I get it in home depot or other home improvement stores? I was able to find only 40W 125V but not 130V - would that make a difference?

Thank you.

As discussed, 120v or 130v will both work. The physical size of the bulb of course must not be larger than will fit in the physical space alotted for it or touch the sides. Smaller is not a concern unless it's too small to eminate light through the grill into the cooking cavity.

You didn't cite the model of the unit so I can't look up the part number and possibly find the details of the designated replacement bulb.

There's no effective difference between a bulb rated 125v vs. 130v (or 120v or 110v). 130v rating is a tad-bit more sturdy for longevity when operated at slightly lower than the rated voltage. Rough-service or longer-life incandescent bulbs typically are rated 130v.

Wattage is a bit more of a concern being that higher wattage pulls more power and generates more heat. Keep the wattage rating at or below the original bulb's rating. Don't replace a 10- or 20-watt bulb in an appliance with a 50-watt, for example.

Thank you @dadoes. Model is UMV1152CAS. What web site do you use to lookup information?

So, I should be more worried about wattage than voltage - got it. I knew I could not go from lower wattage to higher wattage.

The Whirlpool P/N is WPR0713676. It's stated as NLA at majority of sources but photos indicate 40W 130V with a screw-in base as your photo. Any equivalant substitution will work. Search 40w 130v microwave oven bulb for choices. Other brands apparently use the same spec bulb.

thank you @dadoes I was open to find the actual spec for the bulb on the lamp cover. Here are the pictures. It says 120V 40W. Previous owner had 130V 40W.

1. Bulb is 3'' long and 1'' wide. Does the new bulb have to match this length and width or is it okay as long as it fits in the compartment and matches spec?

2. I found this bulb on home depot but it is 130-volt, does it matter if it is not a 120-volt?

I hope you found what you need! : )

For future reference, the "bulbs" forum is for the discussion of flower bulbs, not lightbulbs.
