20 Most Recent Ruud Matching Split Air Conditioner Questions & Answers


Pull disconnect or turn off outside, then reset breaker. If it holds, problem likely inside machine. If it still trips check wiring inside the disconnect or at main panel. Sounds like a direct short, either compressor, fan motor or crankcase heater. You can isolate each component right at the contactor by removing wires to each piece and resetting breaker. Obviously when breaker trips you know what part is bad. 220 hurts, if you are not familiar with electricity call a professional.

When you remove the panel to the unit it turns off the power to it. The reinstalling the panel will reconnect power and allow the unit to reset. So the cheapest and easiest thing you can try is to replace the thermostat. Make sure you see how many wires you have connected to your existing tstat and buy near the same thing. It's possible that the tstat is acting up, not allowing the unit to cool when the temp demands. And turning off power is resetting the tstat as well as the unit. It will be hard to troubleshoot with the info provided so a new tstat will be worth a shot. Hope this helps!

it is what starts yout compressor and fan motor,,,, it causes the current to lead the voltage thereby turning the motors

Have you checked the wiring going to the compressor to make
sure it is not melted? Next, are you
able to put your hand on the top of the compressor? Check to see if it is hot or cold. You might have a bad run capacitor so let the
unit turn on, wait about 5 minutes, turn the unit off, and then tell me if the compressor
is hot or cold to the touch. Next, are
you comfortable with a meter?

A short, a ground, or an overcharge of refrigerant are usually responsible.

Sounds like a short to ground problem with either the motor windings shorting to ground or a high voltage wire shorting.
