What should I check if liquid line is cold and suction line is warm?

Asked Aug 2, 2010, 10:44 AM — 4 Answers
The unit was installed 3 years ago. It was never started until now. I have changed the filter dryer, vacumed, and I opened the txv inside the cased coil. I have sucked the refrigerant back, and vacumed 3-4 times, but the liquid line stays cold and the suction line stays warm. I do know the compressor is on. I just don't know what to check next.

What are the readings on your gauges? You have gauges hooked up right your high side head pressure is how you know if you have the proper charge.

If you have a heat pump unit it, maybe the reverse valve is stuck on heat, reversing the process.Tap it lightly with the butt of a screw driver and put the thermostat on cool.That maybe the problem.

Reply back to aldermat. I did not take temperature of the liquid line but I can tell you when I felt it, it was cold or colder than the suction. But the suction pressure was close to being right on at 115# and 37 degrees. And the unit did blow cold air but only when the compresser ran.
