Fuse blowing on the sharp microwave r-1874

Hi,

I have had the tech out twice, once he replaced the fuse and once the stirrer motor. It's blown again and they say it has to go into the shop to be taken apart.
what do you think? For today I have a fuse and would like to replace it! I've taken apart the panel and don't see where the fuse belongs? I'm looking for a picture online..

Thanks for your help.

Your fuse will be located somewhere close to where the power cord comes in. It's not a regular glass fuse it looks like ceramic with the silver looking ends that's your fuse

test this steps and fix it. God bless you

  1. MagnetronIf your microwave is emanating high pitched or growling noises during operation, the magnetron could be going bad. Normally a nearly silent part, the magnetron uses high voltage and induces the frequency required to cook food. Although normally not a safety hazard to operate, this is a sign that the magnetron is failing and will need to be replaced as soon as possible.
  2. Exhaust fan motorIf your microwave is making a very loud humming noise during operation, it could possibly be the exhaust fan motor. If defective the part will need to be replaced to silence the appliance once more.
  3. Stirrer motorAnother leading cause of a noisy microwave is an expired stirrer motor. With use this part becomes worn and makes a loud grinding noise, which is usually a leading indicator that the part needs to be replaced. The stirrer is a metal blade that is slowly turned by the motor. This action disperses the microwave energy in a random pattern, which heats the food evenly. If the stirrer motor is determined to be nearing expiration, it should be replaced to halt the grinding noise.
  4. Turntable motorA very common cause for a noisy microwave is a worn out turntable motor. This is a relatively easy repair and will put an end to the noise once replaced.

Don't know if this a regular problem with this unit, but for this fuse to blow, there must be a problem further downstream. Maybe with the power supply or the Magnatron.

Not heating


Remove the outer cover (pull the power plug first) and look for a blown fuse. If found, replace the high voltage diode and the 'stirrer' (a fan-like device located within the sheet metal wave-guide near the opening in the cooking cavity where the microwaves come into it). This stirrer has a plastic bearing that frequently arcs over and permanently shorts out the microwaves which blows the fuse. If no blown fuse is found, look for a loose or defective door-interlock micro-switch.

My Sharp R-1874 over the range oven quit working. Is there a fuse?


Yes. Unfortunatly, the fuse is usaully located behind the keypad mounted on a circuit board. You may have to remove a few screws to remove it. hope this helps.

R-1874 shuts down after 59 seconds


That switch is supposed to tell the computer if the damper door is open or closed. If it does not go to zero ohms, the CPU doesn't know what to do. Check the thermistor too...... just in case...

[Identical to earlier posting by stefeckstein]


Check for a circuit breaker on the back. If nothing, pull the plug and remove the case. Look for a blown fuse. If so, look for a shorted high voltage diode in the magnetron power supply or a shorted stirrer bearing located above or beside the cavity area where the microwaves enter. The stirrer is a metal fan-like device with a plastic bearing that often arcs internally. That shorts the microwaves out and blows a fuse. Replace the stirrer.

Shuts down after 59 sec


Chances are you have a bad damper switch or wiring. A sample photo is here: http://207.234.249.73/mwd/damper.jpg It might also be a problem with the humidity sensor or a problem with the control panel, such as corrupted code or bad connections.
