20 Most Recent Sharp R-1480 Microwave Oven - Page 3 Questions & Answers

Some of your story seems impossible. Closed doors do not cause anything. Aging capacitors can cause fuses to go. They also stabilize the magnetron. My bet is the capacitor blew. I have no idea why the fan doesn't work, once the cabinet is open it will become obvious.

If your model is Sharp R-1480, see the service manual here.You can order Sharp parts from Encompass here.

It may be the fuse supplying the magnetron, or the magnetron itself which has failed. Another suspect is the high voltage capacitor in this circuit.Don't try to fix this yourself as the internals of a microwave are dangerous, with high voltages even when unplugged.

Go to your breaker box and reset the switch for the microwave.. that will fix it

test the following steps and fix it.use the VOM God bless you1. 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).

Usually it's not thespring but instead the "latch head", which has a little loop on the backside to hold the spring. The loop breaks off.

The latch head is the long plastic piece with two protruding hooks which activate the hidden door switches.

The door will need to be taken apart (but not removed from the oven!) to get to the latch head. See the attached example photo.
