If you have a bad compressor does that mean you need a new contactor?

Not always. But if a compressor goes bad it can take out the contactor. I have replaced compressors before and found the contactor is still ok. In a commercial application Copeland will not honor the warranty if the contactor is not replaced at the same time a new compressor is installed. Not sure about residential but for a $15 contactor I would not gamble with it.

Can you by-pass the bad contactor relay on your compressor without causing damage to the unit?
Why would you want to? It is in the system for a reason, namely to turn the compressor on and off according to the schedule set by the thermostat. If you bypass it, you would be forcing the compressor to run when the rest of the system isn't, which sounds like a recipe for disaster.
How do you test a good and working contactor?
A contactor is tested by using a device called a Multimeter. By setting the multimeter to ohms and rx1 you can clip both prongs to the coil. If the multinmeter moves the contactor is good. If it doesnt move its bad.
Why would the copper tubing freeze from the outside air conditioning unit?
Poor Airflow due to a dirty filter,dirty evaporator,dirty blower wheel, bad or weak run capacitor, or even a bad bearing in the fan motor causing it to overheat and shut off on overload while the compressor still runs, thus causing the unit to freeze up. On some systems it is possible that when the thermostat is satisfied and the indoor blower motor shuts off, the compressor could keep running if the contactor is sticking for 1 reason or another. Examples of this would be fireants or ladybugs in contactor or just an old contactor that has burnt points that stick some or all the time after running and getting hot. -Brad75-

compressor contactor is bad. probably stuck in the closed position.
Air conditioning outside but compressor does not start?
If its just the compressor that's not starting then it could be bad contactor bad capacitor burnt or broken wire bad compressor lower than normal line voltage If you are not comfortable testing or working with electricity then don't attempt this on your own

When the outside fan on a central air unit doesn't come on will the compressor still kick on?
Yes it can. If the fan is not coming on you could have a bad fan motor, a bad capacitor, a loose wire at the contactor, or a loose wire at the capacitor.
Manifold gauge fluctuates?
This can be a sign of a bad compressor and you will need to run a compressor check first, this can be done without draining the freon....
Your air blows but not cold and you don't need freon in intrigue 98 Oldsmobile?

My ac won't work on 96 blazer?
It is possible the air compressor is bad. You will need to replace the air compressor, so the air will work again.
