It's possible that the module that produces the microwaves is failing. The parts are cheaper but the labor may not so get an estimate before deciding if it's worth repairing or replacing.

I found the fix to the F3H error on another site. Just turn the power to the microwave off for ~2 minutes at the circuit breaker, and then turn it back on. Microwave will start working again then.

You have no power to the unit. Breaker is out or the hot wires into the hood has come apart. The wires coming into the unit usually terminated in a junction box next to the fan housing.Teas it for power an/or reset breaker.

determined from whirlpool that the f2 display is from the control circuit board. the board's problem is intermittent and needs eventually replacing. not covered by warranty. determined that whirlpool has reduced the warranty for the electronic circuits in its appliances from 5 to 1 year. this is great for consumer confidence in whirlpool. have had trouble with 2 other new whirlpool appliances. probably will not buy another whirlpool appliance.
