GE Spacemaker XL1800 JVM1850CH01 vent fan won't turn on


Unplug for about 5 minutes and allow to reset. If the problem persist, you might want to try replacing the control panel (the one that have all the numbers and timers). Good Luck!

Hi. my micromark MM60106 oven seems to be dead ,no red light, no heat ,no fan. power is getting to the switch but nothing works, do I need a new selector switch



Try using the VOM
First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.

You will need to remove the top grill vent first, then you can remove the screws coming in from the top of the grille vent then that will expose a screw holding down the control panel at the top. Remove the screw and remove the control panel. The fuse is located in a little 1" fuse holder just behind the front panel near the top.

My DSpacemaker JVM 1640BJ fan doesn't work


I would wonder if you've had trouble recently with the cooktop lights?

Such failure can cause damage to the control board (which we repair) which can cause either fan to act improperly.

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

Also I would wonder if it's the internal cooling fan or the hood vent exhaust fan?

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the turntable and stirrer won't work, and magnetron will soon be destroyed.

Many brands have a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, & testing.

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.

Accessing some parts may require you to pull the oven from the wall and remove the 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.


You can download GE owner's manuals and installation instructions here.

sounds like the mag fan went out and blew the internal fuse they are ceramic fuses 15 or 20 amp available at hardware stores ,if this blows again it could be the mag overheated,but the thermal breaker should have shut it off before this,thenit can also be your h.v. diode or capacitor shorted

We had a lightning strike near our home and our Ewave OTR microwave quit, nothing works but the light inside and the vent fan comes on automatically. We've been told that there is a fuse that can be...


If the light and fan work then it cannot be the fuse. When the fuse "blows", it stops the electricity totally from flowing into the microwave and nothing will work or respond. The fuse is behind the control panel and this requires several hidden screws to be removed. Also, you must be very careful of the 2000 volt charge that is stored in the wiring further into the compartment behind the control panel. Therefore, do not attempt to open the micro control panel without proper service knowledge.
Because you say the light and fan operate, the fuse (as I stated ) is not your answer; most likely the problem is in the control panel circuit board. The circuit board is like any sensitive electronic component that goes crazy when there is a voltage surge that strikes it such as lighting throughout the house wiring. The board needs to be replaced unless you can have an electronic wizz-kid test is out and repair it , or just by a new board. By the way, the board is not cheap and may be difficult to locate since I understand the the manufacture stopped producing it.

Where are the fuses located? The microwave just died, no power, lights, anything. There is power to the outlet though.


you have to remove the vent grill at top. take out the screw above your control panel. fuse should be in a housing behind panel. if not you have to remove mw wrapper to expose all componets

There is a fuse and cavity thermal fuses as well as one on the magnatron that is supposed to reset itself.. The fuse is behind the control panel and the cavity fuses will require removal of the cabinet. Did you check for power at the plug?

I replaced the light bulbs but they still do not come on and the vent fan will not come on either?


the fan and the surface lights are run through the control via the touch pad. if you tried to replace the bulbs without unplugging the unit 1st you probably shorted the board. this can be checked by lowering the touch control panel by first removing the vent above it to access the panel screw. at this point you can observe the control for burn marks
