SOURCE: Blown Fuse

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

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

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

Chances are that either the diode or capacitor are shorted. Be very careful, the capacitor can store a charge and should be discharged first for safety. Hope that helps...

My Emerson Microwave MW9117W has lost power and was wondering if there was a fuse or something that needed replacing


There are fuses inside. The big thing is to figure out why the fuse went bad. either something shorted and blew the fuse, or it got hot and went bad due to bad connections at fuse holder. or maybe a bad door switch blew the fuse. I have also had fuses just get old and tired., and just needed to be replaced.

My emerson microwave will not power on


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. Use the VOM
God bless you

Normally when you take the cover off, the fuse will be on the right of the oven on the circuit board.

Emerson Microwave stopped working


Have 1 of 2 choices, the main fuse or the control board for the front switches and clock. primary of the small power transformer has opened. Unplug the unit and take case off and measure the fuse with an ohm meter. if u read 1 ohm or less then fuse is good. then measure across the main power plug tips. If read open then the power transformer is bad. Need to replace the board as not sure if transformer is available.

Need a replacement fuse for an Emerson Microwave Model MW8774


Please understand there are some liability issues that Emerson or their parts supplier have in selling you the fuse.

You should be able to find one by going online and searching with the terms you gave, using Google. I just did, and there are a number of hits to choose from.

Try Sears Parts Direct or Repair Clinic as well. You will need to enter your model number to find the parts listing.

In all likelihood, you have a failed controller board or microwave circuit (magnetron, transformer, diode, capacitor). Be prepared for additional troubleshooting.

REPLACE THE FUSE WITH AN EXACT REPLACEMENT> DO NOT REPLACE WITH A LARGER (more amps) FUSE TYPE.
