My GE 2 in 1 microwave oven always have a blown-out fuse

    What is the full model number from the tag on the unit? When does the fuse blow?

    If it went dead almost
    immediately after pressing the Start pad, that's usually a shorted
    high-voltage capacitor.



    If it went dead
    several seconds after pressing the Start pad, that's usually a
    failing
    high-voltage transformer.



    If
    it goes dead or blows the breaker (or GFI) when you plug it in or open
    or close
    the door, then there's a problem with a door switch or door switch
    mount.

GE microwave oven model#JVM1441BH04 when you close door on switch activates and oven comes on. Only goes off when door is opened.


HELLO.

the problem your are experiencing with your microwave oven is a failed interlock switch.
Be careful when closing your microwave door. Slamming the door too hard is one of the main reasons that the interlock switch is damaged.

Slamming the microwave door shut can easily blow the microwave fuse, but they can also blow due to problems with the interlock switches.
A microwave oven will not function until the fuse is replaced.

Instruction on how to replace fuse on microwave.

1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.

2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.

3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.

4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.

5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.

6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

thanks.

Model # jvm1340aw003 I think it has blown a fuse? Where do I find the appliance fuse in the microwave? My email address: claffertysr@sbcglobal.net Thank you in advance for your help, Mike


If the microwave control panel doesn't light up, then your fuse is blown. unplug the microwave. unscrew the vent grill, (2) screws at the top of the microwave. then you should see 1 screw holding the control panel. after removing that screw, gently push up then out. there should be a metal plate on top of the control panel. remove that plate and the fuse will be in that opening. remove the fuse and check for continuity across the fuse. Replace fuse and plug microwave back in. control panel should light up.

Start button doesn't work for all microwave functions--as well as timer--fuse is ok


Possible causes:

1. No power to outlet (overload or fault in microwave or other appliance).
2. Blown main fuse - likely due to other problems.
3. Open thermal protector or thermal fuse.
4. Defective controller or its power supply.
5. Clock needs to be set before other functions will operate (some models).
