The G.F.I on the units power cord trips as soon as it's plugged in. We have already astablished that it is (not) in our houses electric line or breaker box. It was running fine until last night.

    The breakers in our box don't trip just the G.F.I on the unit itself (the G.F.I that is on it's power cord). I haven't been able to find anyone in our area that services the window a/c's. The unit is aprox 4 years old. Would it be a good assumtion that the unit is going out? Do you know the aprox life span of a unit this size/age. We use it full time June -Sept every year.

It could be a number of things. Anything from a weak breaker to a nearly dead A/C. My guess is a basic service/maintenance call will take care of it. When was the last time you had it serviced?

Depending on the age of the house (breaker box), breakers do wear over time and become more resistive. When you turn your AC on, it gets very hot and that's what typically causes breakers to trip. The breakers trip when they get hot due to overcurrent, or just old age. My personal experience was that my box was so old (1968), the busses feeding the circuit had corroded to about 1/2 the size and basically lit up like a lightbulb when the AC was on, causing the breakers to trip. I had to remove the box. First, a heat pump should have exactly the same cooling capacity as a regular A/C unit of the same tonnage. You should really have your unit serviced yearly to be sure it is working at maximum capacity and efficiency. As to the breaker tripping, it is hard to diagnose without being there, but from what you describe, it sounds more like a problem in the electrical service to the unit rather than a problem with the unit itself, but there are many possibilities, and unless you have some basic experience with electrical work, it is best left to a professional. Your best bet would be to call an A/C company.

Take care.

    As i advice earlier, the best thing to do at this stage and with the numbers of the period of time the air conditioner as served you, the best thing to do is to service the air conditioner, this could be due to dust on some vital parts of the air conditioner, once the maintenance routine is carried out on the air conditioner, it will fix the problem.

Please help my side by side ge fridge freezer is tripping our power I have had it for 2 year we moved houses I left it unplugged for three days in our garage then moved it into the house and plugged it in...

With the unit unplugged remove the machine compartment and visually inspect for and burnt marks or frayed wiring. if non is seen, remove the wiring connectors from one component at a time and re test by plugging the unit back in. This will help you isolate the issue hopefully.
The machine compartment is on the back and the power cord is attached behind it. It is usually connected with 1/4" screws so a socket or nut driver will help you gain access.

Fridge freezer tripping rcd

Ensure it fully dries out before trying it again. Water in the electrics will throw your trip instantly. If it's dry now, and you are having the same problem. check the electrics for a short circuit or earth fault. Usually a compressor earth fault is to blame.

No heat from burners or oven after relocating stove

Hi Ron - From what you have described if neither the burners nor oven turns on make sure the electrical connecting is 240V. The oven light and clock portions only required 115V. The clock and oven light working may indicate an electrical circuit breaker supplying the range is tripped or a fuse is blown. Confirm household circuit is correct and the range cord is properly wired to the terminal block.

Hoover 0910dryer not heating. element replaced not long ago

Hi, the possible causes are: Possible Causes: The wall receptacle, power cord (plug) and electrical supply must be in good condition and wired correctly for the dryer to heat.
  • Supply Issue - Loose or missing connection on supply wire from circuit breaker.
  • Plug Issue - Loose or missing connection in the wall. Defective, worn or damaged wall plug.
  • Cord Issue - Loose, missing or incorrect connection of the power cord to the dryer terminals.
If gas dryer and does not heat, Gas Dryer heats with a gas burner, make sure the gas supply line valve is open.
Also, for electric dryer,
Electric dryers require two 30 amp breakers or fuses in the house electrical box to run and heat. If one breaker is tripped or one fuse is blown, the motor, the timer and lights can work but the dryer will not heat.

The gfci power cord is not lighting up

One of two things. First check the power to the outlet. If this is outside, their is probally a GFCI on this line ether on the breaker or in the house on one of the outlets in the laundry or bath room. Or the GFCI in the cord has gone bad. If you have good power to the outlet and it trips when plugged in their is something wrong in the spa and will need to be addresed. If your good with electric you can check this by going step by step with the power till you find what causes the GFCI to trip. If not it may be time for a repairman. Good luck.

GFI on cord trips out.

Probable cause is a single pole gfi opposed to a double pole gfi.
Use a two pole GFCI circuit breaker on such circuits.
