Re: air conditioner not working
The outside condesor unit is not coming on for a number of possible reasons. First check your breakers for a tripped breaker, even if they appear on, turn the ac breakers off and then turn them back on. if after this, turn on the thermostat, outside you should here the contact switch on the condensor unit humming. if still no power, check for any breaks on your wires going in from the house, still nothing give a call back

You didn't mention if you checked for 115 volts at the power supply to the air handler. The unit outside has its own power supply. A lot of times the switch that is on the wall doesn't like to work after its been turned off and back on for service, also check the blower door safety switch. If the blower door hasn't been put back in place properly and snugly it will kill power to the whole air handler. Hope this helps. Good luck
Doc, the outside compressor could be low on refrigerant gas or the condenser switch in the outside unit is faulty. One of the things that is most overlooked is a faulty wall thermostat. For now, it's a process of elimination to troubleshoot and solve the problem.
Hello, first check if the outside unit is running, if it is then check filter to make sure it is clean and that the blower wheel is clean and not dirty. If the unit is clean then most likely you have a low refrigerant charge due to a leak and will need a hvac tech to come out and fix the leak.
If you haven`t changed your furnace filter do so. If there still isn`t any air flow then the evaporator coil is plugged with dirt and needs cleaned. It is inside your furnace where the pipes from the outside unit connects. As far as the auxilary heat, this is normal when the house temperature drops to far below the thermostat set point and they will turn off when the house is close to temperature and lets the heat pump take over.
Look on the condensor, (outdoor unit) at the very bottom of the rear panel and you should find a red reset button. push it. If that does not solve the problem, and the outdoor unit is running (make sure both the fan AND the compressor are running) then you are looking at a low refridgerant issue and possibly dirty coils.
In that case, clean the coils and have refridgerant added.
It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck
YOUR MODEL HAS A 3-5 MIN.TIME DELAY RELAY IN THE CONDENSER CONTROL PANEL OUT-SIDE. DO NOT ATTEMPT TO FIX-IT YOURSELF ... THERE I SAID IT.
IT IS WIRED INTO THE 24VOLT CONTROL CIRCUIT. THEY DO GO BAD AND OFTEN.
IT IS THERE FOR A GOOD REASON. IT GIVES THE COMPRESSOR TIME FOR THE PRESSURES TO EQUALIZE INTERNALLY TO PREVENT "HARD START CONDITIONS".
RUUD HAS A GOOD WARRANTY ON ALL PARTS 5-6 YEARS I BELIEVE. IF IT IS THE TIMER IT IS INEXPENSIVE ANYWAY.
