Question about Whirlpool RMC275PD Microwave Oven
We are getting an E3 and F2 error code and then the door locks and the broiler goes on (like cleaning mode). It did it first when we were cooking something (burnt the chicken because we couldn't get the door open- said it was "hot'). Now if it is on it will all the beep, lock the door, turn on the broiler and show the error codes, then say 'hot'. We can turn off the circuit, but everytime we turn it back on it does it again, so we can not even use the microwave. Can you help?
Good idea to run at half power. Good thinking. That can sometimes reveal an overheating magnetron.
Does it seem to buzz or hum louder than normal?
If so, you may have a shorted high voltage diode or a bad magnetron. If not, I only suspect the magnetron.
If it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.
If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

We have critical safety & disassembly info (including a how-to video) at our site, linked here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

That's what I thought.
We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.
At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.
Feel free to contact me directly (and please remind me of your full model number) for more information & help.

If it's the cooling fan inside the main body of the microwave, I would suspect an open thermistor / temperature sensor. If it's the vent fan (for the grille across the top) then I would suspect the hood thermostat is shorted. The oven should have a "mini-manual" (tech sheet) inside, usually in the control panel frame behind the door open button. It shows these parts and how to test them.
