Whirlpool - troubleshooting

My guess is the bulb burned out. You can probably find the owner's manual online to see if there are replacement instructions.

may be bad bulb, or if bulb blew violently, it may have damaged the main board or relay that controls power to it

That's a common controller problem which I repair on a regular basis.

Feel free to contact me through my site and please include your full model number from the tag on your oven as well as detailed symptom information.

That is referring to the under the microwave light that shines down on your stove. You have full brightness, half the brightness, or the light will be off.

F5 may be a transient problem (grease, impending failure) involving the door switches or *possibly* a sensor error.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

It should also have the fault / error codes.

If the range lights and hood fan never work, then that's a problem on the control board.

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.

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.
