How to replace a lightbulb in a whirlpool GMC275PD mocrowave

look at the top. there may be an access thingy you can remove to get to the lightbulb. replace the lightbulb with suitable replacement. problem solved.

open the microwave. If there is a removable panel on the top, remove it and replace the lightbulb.

Most microwave ovens lamps' outlast the life of the microwave. So, most of them do not have access covers for the oven lamp. The lamp has to be replaced from inside the unit. Also, the newer units tend to use bulb assemblies rather than just a screw in type bulb. Call Whirlpools 800 help line or your local appliance parts store and have them look it up for you.

the timer is more than likely broken. There are no replacement parts and the mocrowave will need to be replaced...or keep the door open when not in use, and use a watch to keep track of cook times

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Then let us know if the hard reset does not fix it.

It may be a bad door switch or switch mount, a failed relay on the control board, or a failed keypad.

We can help further in all these cases.

Feel free to contact me directly for more information & help.

High voltage parts are suspect. You are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!
