I turn on compressor starts working but it turns back of agian


If the motor circuit breaker is popping off as you state, it's either bad or the power supply is inadequate. It's not all that rare for the circuit breakers on electric motors to go bad. When they go bad they either won't reset or pop off at lower and lower amperages. Another cause could be that the motor is essentially trying to pull too much electricity through a line that can't handle it. This would be caused by using too many, to long or too small guage extension cords. Always plug the compressor into an outlet and run longer air lines than use extension cords. On some occasions if you are too far from the breaker box and the lines to the outlet are low guage you can get the same affect.

All compressors dump a little air when they shut off, it's the air in the pump head and discharge tube. This bleed off should only last two to three seconds. If this pressure isn't bled off the motor won't be able to restart when the pressure drops in the tank becuase there will be too much pressure in the pump head for it to start turning again. If you have a longer bleed off or if the motor is struggling to restart most likely you have a stuck or broke check valve. It's the piece where the discharge tube connects to the tank. It's designed to let air into the tank but not back out so the pressure valve can bleed off the air in the pump. On rare occasions you can remove it and clean it out but usually they have to be replaced. You would need Makita Part Number 409004-E.

Hi Just wondering if you could tell me some troubleshooting ideas for an Amana air conditioner--it seems to be getting power--we are hearing a noise coming from the unit indicating that it is getting...


Every air conditioner has a motor called a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself. When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner.

To start a compressor you need a start contactor - relay and a capacitor. The click you hear could be from the contactor, which could be normal OR could mean that the contacts are not staying closed which would not allow the compressor to start.

Air condition problem


What type of thermostat do you have? If the fan is not coming on and neither is the compressor, then is more than likely a problem with the thermostat of control units of the Air Conditioners. The fan will come whether the compressor does or not if the thermostat and control unit are working correctly. Check for twelve volt at the control unit of the air conditioner ceiling unit. (Red Wire, should be labeled)
