SOURCE: Kenmore Micro/Oven fuse keeps blowing

Disconnect the connector to the primary winding of the high voltage transformer. Put a new fuse . If the fuse is not blowing the problem may be in the secondary side of the high voltage transformer. Chek the highvoltage diode, capacitor, magnetron respectively. you can also check the primary winding of the low voltage transformer.

Sounds like a bearing is tightening up when it get heated up with use. Then after a cool down period it works normally until using it heats it up again. Eric

What does F44 error code on Kenmore Elite model 790.4890 mean?


You may be missing a digit in the model number. I believe that this microwave was built by Electrolux for the Kenmore line. The F44 error indicates that the external cooling fan for the microwave is spinning too fast. This can be caused by a blockage. Check if there is anything blocking the airflow. Make sure that the voltage coming into the microwave is correct. If your voltage is too high, then the fan will spin faster.

The fan is part 108 on this diagram: http://www.searspartsdirect.com/model-part/79048903000/0583/0125400/r1009032/00003.html . It's at the back of the deflector at the top of the microwave. This is the diagram for the 790.48903000 .

If there is nothing wrong with the fan (spinning normally), then the problem is between the fan speed sensor and the control board. This should be fixed by a professional.

I hope this helps.

Can a Kenmore Microwave oven Model 401.8504*, 85143 be put on a counter top and used?


Most over-the-range (OTR) microwave ovens have the exhaust fan funning at low speed when the microwave oven is working. This is to keep the magnetron and electronics cool. And it sucks air in from the bottom, so if you just place this microwave flat on the countertop, it won't be able to suck air in, and it could overheat if you use it for more than just a few minutes. But if you can put it on some boards or some sort of grill so air can get to the bottom, then you should be okay to use it as a counter-top model.

Whirlpool microwave fan not working


I would unplug the oven for 2 minutes to do a hard reset and try it again, just in cause there was a glitch.

Without knowing your full model number from the tag on the oven, I would wonder if it has a separate internal cooling fan from the hood vent exhaust fan. It could be an unrelated issue.

For more free DIY and other help & advice, feel free to contact me with your full model number and FCC ID number from the tag on your oven.

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)

  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.

The unit seems extremely quiet and fills with steam when cooking. I'm concerned the exhaust fan on the microwave isn't working properly. I just got it so I can only compare it to other microwaves.


How old is the oven ???, Is the food saturated with water ???, Is the exhaust clear from any obstacle ??? Do you feel air coming out the exhaust when it's running ??? (compared to when it's not) if it's a new model it is NORMAL, newer (expensive) models tend to keep moisture in the oven... they are built that way to prevent drying out food (on the plate rim) or (if it's fresh from the box) check for forgotten PACKING material that could prevent the oven from exhausting properly... you could also call the manufacturer/GE to check with them as well...

Cheers!

Kenmore microhood


"Microhood" seems to be a slang term for the "microwave hood" (hood fan or exhaust fan) which is normally part of an over-the-range microwave oven or range. But these should be available separately, as I seem to recall. I would contact home centers such as Lowe's, Home Depot (if they still exist), etc., or a local appliance store.
