Microwave Range lights are out.

Range lights will not come on. New bulbs, new sockets, vent fans work. Is it the smart board or what? How can I check?

Yes ,it is the internal board that unfortunately controls most of the functions on this microwave , but if its still under warranty your safe ,if not you can still call customer service of the manufacturer and let them know it has never worked and they will probably send you the part free of charge , hope this helps , sincerely glenn

I have a GE JVM 1870 over the range microwave with the active vent. The interior light is out which is a simply fix. How to I get to it?


follow this steps and fix it. God bless you
  1. Light bulb If 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 board If 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.

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 .

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 change the bulb on ag821azh microwave x2


follow this steps and use the VOM for fix it. God bless you

Light Bulb

If the microwave light bulb is not working it is usually located behind the upper grille and behind an access panel, and above the lower panel. On counter top units you will need to remove the outer cover to get to the bulb. If that doesn't solve the problem check the on-off switch, and control board

Main Control Board

If the microwave light bulb is not working check the light bulbs, sockets and wiring. If they are good the main control board might be defective.





Light Bulb Socket

If the microwave light bulb is not working and a new light bulb doesn't solve the problem, the light bulb socket might be burned out and need to be replaced.

Tappan microwave vent motor and cooktop lights not working


see this test . God bless youThis microwave oven repair is only for over the range(OTR) models. First, with microwave still installed, gain access to the control board and check for voltage from the fan relay. If you are not getting voltage from the fan relay on the control board, and your display says fan is on, then you need a new control board.
Again, this microwave oven repair is for OTR models. If you know your light bulbs are good and your display is telling you that they should be on, check the light relay on your control board. If no voltage is found at that relay, then replace the control board. Otherwise your problem is in the light socket, wiring, or wire connectors. You can get to all of that by unscrewing 6-8 screws under the unit and taking the bottom panel off.If voltage is present and the wiring that you can see looks good, then you will have to take the unit down and test for voltage at the fan itself. If the voltage is present there, then test the motor itself and/or start capacitor for the motor. The fan motor assembly will slide out of the top of the unit after you take it down and unscrew 2 screws. Below, in the list of component testing, you will see how to test the motor and start capacitor. get the part from

Lights on bottom don't work. Sockets fell apart and vent fan now does not work. A bulb blew out , then all of this happened.


We see and repair this a lot. The problem is on the control board, which we regularly repair for $39.95 nationwide.


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.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.


We'd also recommend buying top-quality bulbs.


They can blow if subjected to vibration such as door slamming or a weak floor, or electrical fluctuation, especially if they are cheap bulbs or they are left on all night.


Instead of having the board repaired, you can order a new control circuit board / smart board if that's economical, and since your sockets are bad, they will need to be replaced, too.


You can find links to helpful exploded view diagrams and part ordering help here. I recommend that you bookmark that link to your

favorites.


There's a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes.


If you're changing the board yourself, you'll need to detach the keypad connector:

Some connectors will have a lock.

Sounds like the ERC board failed. It maybe covered under warranty, check that first cause a new ERC could cost around $150-$200. Anything electric can cause the .."what the*^&% just happened syndrome.

Range light and oven vent fan


This usually indicates damage to the circuit board of the control unit assembly. We repair these control units nationwide for only $32.50 postpaid. If you decide first to remove or replace the bulbs or check the sockets or wiring, please unplug the microwave first. Failure to do that is usually how the boards get damaged. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can usually find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383 BUT - I don't recognize NN-2501 as a valid model number. Could you confirm that? Thanks!
