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


Normally the problem is not the spring, but a broken spring mounting tab on the door latch head (hook) assembly or the inner door panel.

If it's the door panel, it's usually easier and cheaper to use epoxy and some kind of hardware to fashion a new spring mount.

The door latch head (hook) is easy to replace or repair if that's the issue.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

No use on fixing the oven. They cost $150-300 so why bother?

I would guess that the boiling water may not have been the cause ...
If you are lucky ... try this first:
Unplug or turn the circuit breaker off (if it is a built in unit). Wait an hour and then repower.
Odds are that will not clear things up ... but it is easy to try. Probably one of the electronic internals broke.
A number of different internal component problems could cause this heating failure in the microwave. It could be the magnetron, the high voltage transformer, the PC board, the diode, and the capacitor. This type of problem will need to be diagnosed and repaired by a service technician. Microwaves are inherently dangerous to service. This type of repair is not something that you want to try to do yourself. Internal capacitors in the microwave can retain a lethal electrical charge even when the microwave is completely unplugged. A microwave radiation leakage test should be performed on the unit using proper testing equipment following any internal component repair.

First I would suggest a "hard reset". Simply unplug the oven for a minute or two, then try again.

If it still fails, it may be that the keypad has failed, or there is a bad connection due to moisture, grease, etc.

This is an Australian model, so it's hard for me to give more specific information.

But one some US models the LCD and keypad connect to the circuit board via a rubber "zebra strip" and losing that connection can result in a loss of display segments and / or key response.

I've attached a diagram showing where one can clean to restore operation in this case.

normally you look for the clock ot watch icon. Pressing it once will give you the option for 24 hours setting. Press it twice and it will give you the opportunity to set to 12 hours setting. Using the no. keypad, punch in the time and then repress the clock icon again.

Door switch error. DO NOT USE like this.

To set the clock to 4:30, for example:

CLOCK > 4 > 3 > 0 > CLOCK


- or -

CLOCK > 2 > 4 > 3 > 0 > CLOCK
(the two means you're setting the clock, as opposed to 1, which would be to set the timer)

They is one of the DOOR SWITCH need to replace

Yes it is safe to continue using the Microwave as long as the integrity of the glass is not compromised and the pitted marks do not exceed 1/4 inch. The RFwave generated by the magnetron is a pretty wide RF wave beam.

If your really concerned you can take the unit to any appliance service center and ask that they perform an RF leakage test. There is really no other way to know if your leakage is within acceptable limits. I can tell you from personal experience that the ony microwave I ever saw demonstrated excessive leakage had either been dropped and had hinge or latch damage.

If your really worried about it and can not get to a service center you can do this test:
- Wrap a tall empty glass with a sheet of aluminum foil and place it about 3 inches away from the microwave in front of the area you where noticed the pitting.
- Run the microwave with a GLASS filled with water of equal size for 1 minute.
- Stand back 3 to 4 feet and watch for any signs of a spark on the aluminum foil.
- As soon as the microwave shuts off check the dry foil wrapped glass for any signs of heat.

(No heat.... no problem. Sparks or Heat = repair time.)

Thanks for choosing FixYa.
