You can but the unit will have not control over temperature, and you can cause the unit to freeze up or slug the compressor w/ liquid refrigerant causing premature compressor failure. I would recommend replacing the thermostat if it is not holding proper temperature, but if dead set on bypassing it use a volt/ohm meter after unplugging it to find the normally open contacts and wire those wires together taking into consideration that the fan must run constantly with the compressor.
It sounds like your compresssor is shutting off on an overload. After the overload cools down the compressor comes back on until the overload heats up and shuts the compressor off again.The fan keeps running as it is not on the same circuit as your compressor.
Probably overheating. Check the outdoor coil and see if it is stopped up with dust, grass etc. If so, disconnect power to the unit, and clean the condenser coil with water or air. Be careful not to bend the fins if you use a water sprayer.
Take it back to the dealer and have them fix it, could be a compressor froze up or a fan froze up. If you disconnect the compressor and turn it on and it trips the breaker the fan is probably
bad. If you disconnect the Fan and turn it on and it trips the breaker
it is you compressor.
Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.
I believe the problem in lies in the dual stage heat mode setup on the thermostat, but the unit going into defrost does make the unit act kinda strange. Even more so than other types of equipment. I would suggest hiring a licensed HVAC service technician if the problem cannot be resolved by yourself.
Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.
