Did this occur after a failure of your cooktop lights?

Or is there is buzzing noise present when the oven is not operating, or when the door is opened?

If so, then the problem is on the control panel, which can be repaired economically.

There is a a YouTube 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.

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.

When turning Fan on (any speed), top vent grille blowing lots of air, but not pulling air underneath


some microwaves vent to the exterior. check outside for a vent. If it is a recirculating model, perhaps the filters are plugged, the vent pathway is blocked (packaging material) or a loose panel at the back so that the exhaust fan air is leaking out somewhere else. I don't know what else it could be unless the fan is loose on the motor shaft and the fan motor is running but the fan blades are not moving air.

"SE" error means you have a shorted membrane keypad.
On this model, the membrane keypad is not available as a separate part, so the control panel frame assembly (which comes with a new keypad) would have to be ordered and replaced.

It's actually a pretty simple DIY repair.

The frame assembly is part number W10258190 and you can get it for $67.98 (subject to change) from the Pros here. You can also order the thermostat (part number WB27X10567 ) from them.

Their is a video here 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.

Some connectors on the relays have a lock:

Microwave VENT fan keeps running


I would say you replaced a good hood thermostat (or "TCO" / thermal cutout) with a new thermostat of the wrong type.
The oven cavity TCO and the magnetron TCO will read zero ohms continuity when tested.
They are "normally closed" devices.
But the hood vent exhaust fan's TCO is a "normally open" TCO or thermostat, so it should read open or "infinity" on a continuity check.
If the temperature under the microwave gets too high, the hood TCO opens, which turns on the vent fan until it cools back down.
I would bet that only your fuse was blown.

Exhaust vent won't turn off


I've found information on models FMV145KB3 and FMV145KS3 but not FMV145KF3, but this should still apply.

This will be either a shorted hood vent thermostat on the floor of the chassis of the oven, or a shorted triac or relay on the control circuit board.

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.

d:%5cele%5crepair%5cmicrowave%5cge_hotpoint%5cmini_manual_behind_grille_small.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If it's a thermostat, you should be able to get it
here.

If the thermostat is good (reads open) then the problem will be on the control circuit board.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

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

Active vent keeps opening and closing though fan is off.


When the unit begins the never ending opening and closing cycle, turn the vent fan on for a few seconds and then turn the fan off. This seems to stop the active vent from opening and closing. If this is GE quality, this is the last thing that I am going to purchase. GE refrigerators are garbage and now I am having problems with a new microwave oven.

I have an LG LMVH1750ST microwave convection oven. When I activate the fan for cooking purposes and then try to turn off, it does not respond. I have to pull electrical plug and reprogram for one minute....


From the owner's manual under OPERATION "VENT FAN":

"If the temperature from the range or cooktop below the oven gets too hot, the vent fan in the vent hood will automatically turn on at the 4-Speed setting to protect the oven. When this occurs, the VENT ON/OFF pad will not turn the fan off."

You should check your "vent fan auto time set" setting.

Here's one thing to try to set it to turn off after 10 minutes:

Touch the Vent ON/OFF pad, then touch the "5-SPEED VENT" pad until "level 4" appears in the display, then touch "AUTO TIME SET" the desired number of times.
