Goodmand 2 Ton Heat pump was not working. The condensor fan was not turning. Replaced fan and system ran. But I got odd reading Below are the readings:
High Side 132 (=75 degrees)
Low Side 75 (=44 Degrees)
Temp Outside: 99
Temp Inside at return: 88
Wet Bulb: 75
Temp after evap: 68
Temp drop across Evap: 20 (Seemed Good)
Target Superheat 22 (3*75 - 80 -99/2) = 23
Temp on suction line = 68 (though fluctuated)
Actual SH = 68-44 = 24
Temp on Discharge line = 105
Subcooling = 105 - 75 = 30
After awhile clouds rolled in and the outdoor temp dropped to around 92 and the head pressure dropped to around 95. I did not retake all the measurements. I do not understand the low head pressure. I am thinking about taking another set of guages to double check.
Also when taking the suction line temperature every once in awhile it would drop to 52-55 degrees and then raise back to around 68 degrees.
Any suggestions on what to check?
