if you know that you have high voltage power at the condenser, try looking down at the bottom of the front panel for a red reset button. this is a manual high pressure reset switch.

did you replace the contactor. if so, you need to verify the control coil voltage. should be a 24v coil. you need to also check to verify you are getting 24v at the contactor coil.

its the block where all the wires are connected.

over load from service

did you change the air filter and do not set it below 70,the tstat is not a gas pedal its works like a light switch, on or off, also please don't use your breaker as a switch its a safety device and will be damaged over time,If the unit starts to form ice (and it should never do that)set the tstat from cool to off and the fan button from auto to fan on,this will speed up the thawing

Hello Hottie, start by verifying that the outdoor A/C breaker is in the on position. If it is then there is a problem inside the unit (most likely a split capacitor failure) and you should have an HVAC company help you out because that is HIGH voltage.

It sounds like it could either be low on refrigerant or the compressor has stopped working. Start by verifying that all the breakers and controls are in the on position. If the outdoor unit is running but you have no cold air, you may need a HVAC company at this point.

I suspect a bad run capacitor or fan motor. This is a split run capacitor unit. There is a terminal on your run capacitor for the compressor and also one for the fan (the metal canister with wires on it).I'm assuming that the compressor works, but the fan doesn't. Speaking to a novice without a multi-meter, so you won't be able to take continuity readings on the motor windings. I would say to you "just buy a new capacitor" If that doesn't solve your problem, call a tech. Before replacing it, be sure to disconnect the power first, and then use an insulated screwdriver or some other insulated tool (pliers, etc) and short together the capacitor terminals, because they do store a charge. Do this before attempting to remove the wires from the terminals. Whether or not the motor is good, you didn't waste your money. A new fan motor should have a new capacitor anyway.It could also be as simple as a broken conductor. Give it a good visual first, before attempting any repairs.

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

Welcome to the world of Ruud! Ok James heres the deal. It sounds like the condenser fan motor has failed. Its not a repairable item but the motor is not too expensive. Disconnect the main power at the fuse block on the side of your house next to your a/c. Remove the screws that hold the top fan section and carefully turn the fan/panel assembly over taking care not to stress the wires. Determine how the fan is mounted (probably 4 screws) and go find your new motor. Both Rheem and Ruud use the same motor mounting. Most a/c supply houses have a motor that will fit or go to graingers. Make sure you get a matching run capacitor for that motor. It will have separate wires and not share any wiring with the old capacitor. The old capacitor will have to stay in place since it is also connected to the compressor. The old motor will have 3 wires and the new one 4 (2 brown for the capacitor and 2 others to put on the contactor that the compressor wires go to). If its a heat pump it could be a board and youll need help. good luck

What model is the unit?

Not really. You have alot of moisture in your home and it is removing it is all. Only problem with to much liquid is if it is forming on the lines as condensation and dripping on your ceiling. Make sure your drain pan is clear of any gunk and the drain pipe allows good flow to the outside.
