It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel, between the door switches, or inside near where the cord goes into the chassis.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

Or another common problem, is surge damage on the control circuit board. We regularly repair these control units for customers nationwide with our guaranteed $39.95 service.

Samsung Microwave Oven SMH7159 No Power


The power outage may have been accompanied with a power surge. That can happen with lightning strikes, or if a large inductor (electric motor or equivalent) happened to be on the same power line at the time of the outage. There's a good chance a surge took out the control panel.

No power to Samsung SMH7159 Microwave


There is more than one fuse. Look for a second one.

Hi I have a Samsung SMH9187 micowave that is dead (no display, light, fan, mirowave).


Sounds like the main fuse blew. It's either near where the power cord enters the cabinet, or behind the control panel (if an over the range unit).

You may also have some type of failure in the high voltage circuit; based on your description of the symptoms.

Good Afternoon Friend,

I understand that you had a power surge in your RV and your Frigidaire microwave, model# CFMV152CLBA, does not have any power to it. I also see that the outlet your appliance is plugged into has power. I suggest contacting your local authorized technician, mainly because you are dealing with your microwave. The technician will be able to diagnose your appliance and determine why it is not responsive. Hope this is helpful.

-Best Regards-

Vent blower won't stop


I had the same problem with the fan not wanting to shut off after the repair. Once I set the clock though I was able to push the button to shut the fan off. So try setting your clock first and see if that helps.

Loud popping noise after being plugged into 50 amp power source possible power surge unit in rv unit light still works but no power to make unit work.


What happens a lot in these RV microwaves is that a surge will damage the circuit board and sometimes also blow the low voltage transformer.

These are problems we can usually take care of for $39.95 and $54.95 respectively.

Our sylvania microwave model sr11092b received a power surge that blew the internal fuse and would not run (it also fried the power converter in my rv)\r\nReplaced power converter, replaced internal fuse...


I had the EXACT same symptoms with my Sylvania SR1109sb after a power surge.
After some digging around I thought what the heck let me try holding down the Reset button and do a power off/on cycle and what do you know it worked !!!
Just pressing the Reset did nothing until the cycle off and on.
