When i open the microwave, the fridge turns off?

Question

Everytime I open the microwave door, the fridge turns off.

Why is this happening?

whenever it happens, I have to turn the fuse off and turn it back on in oder to get the microwave and fridge back on.

To my knowledge, the microwave and fridge are the only things on that circuit. The stove and dishwasher still work, even when the fridge turns off

Answer 1

Is it an old-fashioned circuit breaker that's tripping, or is is a Residual Current Device (RCD) (also known as Residual Current Circuit Breaker (RCCB), Ground Fault Circuit Interrupter (GFCI), Ground Fault Interrupter (GFI) or an Appliance Leakage Current Interrupter (ALCI))?

These devices are much more sensitive than the older circuit breakers and trip at the faintest sign of an electrical fault. In case you're not familiar with them, you could grab a live wire on a circuit protected by an RCD and (if it's working correctly!) it would trip before you even felt a shock.

Apart from a label on the device, the most obvious difference between a circuit breaker and RCD is that the latter will have a button marked "Test" on it.

If the microwave's circuit is protected by an RCD, it could be a relatively small problem that is causing it to trip (as I've said, they are very sensitive), but, regardless of whether it's an RCD or circuit breaker on the microwave's circuit, then the fact it is tripping every time you open the microwave door (which turns on a light, right?) indicates that there is an electrical fault in the microwave and you really shouldn't be using it.

Try moving the microwave to socket you know for certain is on another circuit from the fridge and open the door. If the other RCD or circuit breaker trips, then you can be certain that it's not a problem with the RCD/CB, but rather that there is definitely a problem with the microwave and it needs to be repaired or replaced. If it doesn't, then try plugging something like a hairdryer into the microwave's old socket and turning it on. If the RCD/CB trips, then you can be fairly certain the problem lies with it. They're normally very dependable and have a long life, but circuit breakers and RCDs are known to go bad, particularly if they are habitually run at something close to their maximum rated current. Replacing an RCD or CB is quite straightforward, although the task is not without it's risks and so is something that should be attempted only by someone who understands the dangers and how to minimise them.

Answer 2

It sounds like there's a circuit breaker tripping, saving your life.

Answer 3

Either your phone is ringing or you have too many things plugged into the circuit.  I would bet on the circuit.  You should check the size of the fuse you're using.  Check the rating on the refrigerator and the microwave.  They should not total 30 amps together.  If you have 30 amps between them, make sure you are using a 45-amp fuse on the circuit to ensure you're not overloading the fuse.  If you're using a circuit breaker, check the breaker for wear.  If the circuit breaker is old, it may be weakened by time and erosion.  In any case, make sure you don't have too much going on at any given time on that circuit or you will be putting out flames.

Answer 5

HA HA get over it HA HA

Answer 6

There is a short circuit in the microwaves wiring, probably to the door switch or light socket.

If the micro isn't old, have an appliance repair person come out and fix it.  If it's old, get yourself a new one.

FYI-You don't ever increase fuse or circuit breaker ratings, that causes overheating of wires and can lead to a fire.
