Hello. It would be nice if you can help me. I bought a house in 2007 with a Frigidaire split system heat pump central air conditioner apparently new. Now that it broke down and needs a new compressor, I would like to know if it is under warranty. Model: FT3BC-042K Serial #: FTA010400805 Compressor code:KB

i would invest in a new unit the cost to get this one repaired will add up and theres no guarantee they will fix the problem

Check each screw on your compressor to ground (compressor case). Should be very high resistance Then check the resistance across your teminals on the compressor to be sure it is not shorted. Then check the wiring to your capacitor (The big one). I ran across this just last week. The mechanic didnt have the capicator wired correctly. If it is brand new it will have a wiring schematic somewhere on it.
Dont leave the compressor on very long, but turn it on long enough to get a voltage reading across the terminals. I assume it should be 240 volts. If you have check all of this, they make a jump start gadget to start a stuck compressor. They sell it just about everywhere. Let me know how this comes out..

When it hums, is it running? Or does it not run when it hums? I'm assuming it runs when you say you have to turn the therm off to get the noise off.. If it's humming and not running, you have big problemo friend..
