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

  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.

The internal 8a ceramic fuse has blown on my Sharp platinum collection 900w microwave oven, model R-957. fuse is marked F8AH 240V and is located on a small circuit board inside the rear of the oven. is...


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.

Remove the outer case 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 waveguide that is over/beside the cooking-cavity microwave-energy entry opening). The stirrer has a plastic bearing that can arc through and short out the microwave energy. Replace the fuse after repairs.

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.
