Whirlpool mh1150xm range hood light out

The over the stove light is not working. New bulb, select touch pad and a beep sound is made so I know the lamp is selected. Are there any fuses on the ckt board? Is there a wiring diagram available?

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.

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.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Whirlpool microwave model mh1150xmb


please test this steps and fix it. God bless you

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.

Light bulb above stove under microwave hood


According to the GE manual it is a 120 v 20 watt halogen bulb, the GE product number is WB36X10213. That is the cooktop light/nightlight that would be on the stove hood. HTH!

Hi, I have a Maytag stove and unfortunately have lost my manual. In the last couple of days there has been an alarm going off with F1 appearing on the display panel. Once at 5:30 am and at 1:00 am. Could...


With Maytag Ovens the F1 error means Defective touch pad or clock (ERC). This simple test will help determine whether the ERC (Electronic Range Control or Clock) or the touch pad is defective when F1 error code is present. (If you don't feel comfortable doing this yourself you need to arrange a repair technician to look at it for you)

1. Disconnect power to the range (unplug the range power cord or turn the power off to the range at the circuit breaker). It is very important that the power to the range has been disconnected, so please double check before continuing.
2. Gain access inside the control panel.
3. Disconnect the touch pad (also called keypad or membrane switch) ribbon from the ERC.
4. Make sure there are no lose wires, or anything else that may cause a short when power is turned back on. Assemble the control panel back the way it was.
5. Turn the power back on.
6. Wait for at least one hour to see if the F1 code comes back (usually accompanied by a beeping sound).
7. If F1 comes back, replace the ERC. If it does not, replace the touch pad.

Regards, Kat (please leave feedback, thanks)

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 with a one year guarantee.

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, cooling fan, turntable, and/or inside light operation, too.

Details of our service are at our Web site, along with a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you prefer, you can order a new control circuit board and install it.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below), remove the damaged circuit board and insert the new one.

I have Model #JER8750AAB Serial#16776012WK When uising the self cleaning feature, oven stopped and F1 displayed on stove ??


  1. Disconnect power to stove
  2. Gain access to the back of the clock (electronic range control or ERC).
  3. Unplug the touch pad ribbon connector from the ERC. This will be a flat wire approx. 1 1/2" to 2" wide.
  4. Make sure everything is clear and will not short out when power is turned back on.
  5. Turn power back on to stove.
  6. Watch for the F1 and listen for the beep.
  7. If you get the F1 and beep, replace the ERC.
  8. If after approx. 30 minutes you do NOT get the F1 and hear the beep, replace the touch pad.

The range-top light blew and now replacement bulbs


My Whirlpool/Roper microwave/hood combo has the same problem. I replaced the bulb twice, checked the bulb and it works, but not in the microwave. I wrote to Whirlpool asking about the problem. Haven't heard from them yet.

Microwave Hood/Combo


This is a common problem with the control panel assembly, which we repair nationwide for $39.95. This is most often caused by not disconnecting the microwave from the power line when removing or installing a bulb or by the filaments shorting when the bulb blows. If you or a friend decide to disassemble it to send the control panel in for repair, we have *critical* safety & disassembly, info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams by entering your full model number (without the suffix) here: http://tinyurl.com/gv383
