Upon arrival I met Troy on job and after running system for some time we found that the suction line is getting too hot because fan isnâ€™t moving enough air. Increased fan speed and checked operation of HeatPump. We never saw unit lock out or fault during test, only when we arrived we found unit was locked out on high pressure. We also verified that furnace and HeatPump are not running at the time same. We asked customer to update us after adjustments were made.
Upon arrival I found cube tripping in water flow. Tested unit and found bad flow center pump. Quoted customer to replace and he approved. Customer also mentioned that aux heat is tripping breaker. Found aux heat is pulling normal amps, 44. Breaker in unit is not tripping, 60amp. Breaker at service panel is tripping. Informed customer to get main breaker replaced at panel before returning to replace flow center pump. Customer paid half. Office please call to schedule return. Returned to replace flow center pump. Customer informed me breaker has been replaced and it hasnâ€™t tripped since. Verified left side flow center pump was bad. Replaced with new and purged air out of lines. Ran pumps only and checked amp draw. Put gauges on system and ran heat. Checked amp draw during both stages. Normal refrigerant pressures and temps. Normal loop pressures and temps. Normal delta air evap coil. Unit is operating normal at this time.
Upon arrival I went to basement unit and found drain safety switch laying on its side and not in bracket. Put in correct place and then went to thermostat. Stat has power and is showing currently 60 set for 65. Went into settings and found dual fuel has been set up at 34 degrees. Raised to 50 and furnace fired up. Tested both stages of furnace and then put dual fuel settings back to 34. Ran HeatPump and checked operation. Recalled fault code status and found high pressure fault and lockout. Tried to test defrost but control board uses algorithm to run defrost, cannot force. Checked thermistor and found correct reading. Found unit has 21 degree delta air temp at Evap coil when outdoor temp is 45. Do not see a reason why unit tripped high pressure unless that was an old fault during installation. Let system satisfy in HeatPump mode then checked thermostat settings again. If HeatPumps struggle to keep up during cold weather we may need to increase dual fuel temp setting. Customer wasnâ€™t
