Hello all,
I was at my mother in-laws yesterday when i felt cool air blowing on me i went out to heat pump and felt suction line it was out door temp so I pulled disconnect,went home and got some tools. it was about an hour later pushed in disconnect with amp meter and gauges hooked up compressor fired right up pulling 7.75 amps 118 suction and 320 head pressure for about 12 min; I was just getting ready to load my tools up when the unit started straining the suction pressure stayed the same but the head pressure started climbing. The head pressure was at 575 when I energized the reversing valve for a few min. then swithed back to heat it again ran for about 10 to 12 min. and did the same thing does this sound like the txv is sticking?
The system is a 410a 2ton coleman I will get model # next trip over. I pulled disconnect and swithed to emerg. heat. Thanks for any help
