JENN Air bulb replacement problems

I replaced the two 40 watt bulbs on the bottom of my JENN AIR JMV8100AAB over counter microwave and still the new bulbs will not light. I didn't unplug the microwave while replacing them. Do I need to get my control panel repaired. When I press the light on and off button on the control panel I hear the sounds, but it does not turn on the light.

Thanks, Louis

We see (and repair) this a lot. The problem is indeed on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.

At our site, 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.

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.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Controls, heating and turntable function normally, but there is an intermittent failure (approx 80 of the time) where the interior light and blower do not function when the microwave is operating .


follow this test 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.
2)
  1. Exhaust fan motorIf your exhaust fan motor is not running, there are a couple of things that you can check involving the motor to locate the problem. After removing the fan motor, you can manually attempt to turn the fan blades with your hand. If the fan motor is working properly, the blades should spin effortlessly. If this does not occur and the blades are taught, the motor will need to be replaced. Secondly, the fan motor itself can burn out due to time and usage. Using an ohm meter, the exhaust fan motor should read open for continuity. If it does not, then the fan motor has expired and will need to be replaced.
  2. ThermostatAnother part that could cause the microwave exhaust fan to not work is a faulty thermostat. A thermostat gauges the air temperature, which activates the exhaust fan when required. If this part becomes flawed, the exhaust fan will not energize and the thermostat will need to be replaced.
  3. Main control boardIf your exhaust fan is still not working and the microwave fan motor, wiring, and thermostat are operating accurately, the root cause could be with the main control board. Replace the main control board.

How do I replace light bulb on my Jenn-Air microwave?


Hi.

You will need to partly disassemble the oven by removing the outer cover held by screws (the cover part 2 on the first diagram). once there you will see the bulb hand side, located on the right (the bulb is part 6 in second diagram).

Before disassemblying the appliance disconnect power, by tripping circuit breaker or unplugging the power cord.

Here the replacement part for the model JMC9158AAS, listed in title: PS391758 .
Diagrams below are also for Jenn-Air JMC9158AAS.

If you have a different model, use the links listed here: Where do I find parts and diagrams for my appliance?

Here the diagrams. Click on the pictures to enlarge.

Diagram 1:

Diagram 2:

Unless you are a technician or a trained DIYer, better ringing the number listed on the owners manual to call service support. A badly assembled microwave will be dangerous for your health. The capacitor inside the microwave can also release dangerous discharge, take care and observe safety prescriptions while disassembling.

Regards.

HOw do i replace the inside bulb?


Hi. I just told you, there is no acces for the bulb in microwaves. Bulb replacement is not supposed to be a user level maintenance operation. You will need to remove the microwave outer cover to replace the bulb.

Here again my instructions: How do I replace light bulb.

Interior bulb went out , and it's an over the counter mount. How do I get to the bulb ?


Remove the top grill cover by gently pulling out on it and down on the right side. Remove the filter that is in the middle. Look at the metal cover, push back on the plastic tab and pull the metal clip toward you. You can now gently lift the cover off expsing the lightbulb and replace it. Simple and easy, no tools needed.

Hi! How do change the bulb in a Goodmans GSS20 microwave?


If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

If it's an over the range type, remove the vent grille across the top and see if bulbs can be accessed there. There may be a panel on the bottom covering the light(s), instead.

If not, chances are you'll have to remove it from the wall, then remove the outer cover. If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Once it's out of the wall, the outer cover (wrapper) will need to be removed, just as you'll need to do on a counter top model.

The screws you need to remove should be pretty obvious, and a special driver (such as a T20H Torx type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.
