Sharp Carousel Microwave R-1460A no power, door switch went first

This appears to be an Australian model and these are the only spares I can find. They do sell the latches. If the hinges are damaged and causing this, you will feel movement. Looks like it is time for a new one.

I've had a similar problem with a 1983 Sharp Carousel microwave. It turned out to be a faulty door micro switch, the contact didn't stay closed inside it for very long.

The service manual is here:

You can get Sharp parts from Encompass here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
See http://www.microtechfactoryservice.com/cap_test.html

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
See: http://www.microtechfactoryservice.com/xformer.html

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

It sounds like one of the door switches has become defective, each must be disconnected on the one side and tested with a digital meter using the ohms scale.

Check and change door interlock switches or check for condensation problem on control panel, (internal).
Hope that helps.

It's probably a bad door switch or door switch mount, probably the top one, which is the door sensing switch.

Take it immediately to a local Microwave repair shop...looks like one of the circuits may have gone...otherwise switch off from mains

Check or replace your door switch.

Itmay be the fuse, which is usually located behind the grille or on thefloor of the oven behind the control panel or between the door switches.

Ifthe fuse is good, it may be an open thermostat or thermal cutout (TCO)/ thermal fuse on or near the magnetron or on top of the cavity / bodyof the oven.

If it goes dead for a while during or after cookingthen comes back on, the magnetron is probably overheating and causingthe magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

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.

Ifit goes dead or blows the breaker (or GFI) when you plug it in or open or closethe door, then there's a problem with a door switch or door switchmount.

If it's intermittent or random, it may be a badconnection, usually on the control board or a loose fuse holder, oreven an intermittent fuse.
