He could not detect the leak using sniffer or see any obvious oil leakage but surmised based on experience of know problems. Problem: My outdoor air conditioning unit’s high-pressure switch trips ever so often. This sounds like you might have a slow blower motor or your indoor coil is dirty. We sell many different contactors on the following page: https://arnoldservice.com/product-category/air-conditioner-parts/ac-contactors-heat-pump-contactors/ Yes, this could very well be a low pressure (low refrigerant) switch that is cutting the unit off for protection. The unit is 3 years old and is a nordyne unit. 3. The indoor filter is clean and coils on condensing unit are clean. The compressor is Coperland scroll ZR34K3-PFV-130 A new Evap coil (RCSA … How our day has typically unfolded in the past few days: the outside unit cools/runs fine in the morning hours, until about 3/4pm (it does not matter if it is 70s outside or 90s), then does not run (the thermostat kicks on and the attic unit blows air but the outside fan does not come on), but then the outside unit is operational again about 4 hours later in the evening. - Verify communication cable connection between the inverter and ICC is complete. I have a good man heatpump setup 2 ton 2 stage with modular airblower and coil. We would love to answer your questions and have your business!

Recover refrigerant. If the high-pressure switch continues to flash the high-pressure switch fault code then I would like to suggest that you or a service tech install gauges to see if the pressure is actually high or if the pressure switch is bad. Greetings, I have rheem heat pump unit that heats and cools with air handler inside the house. Any advice? Hi Mr. Arnold – I have an old Tempstar 5500, Model CH5524VKA2 installed 1993. Is there power going to the compressor windings when it stops or is something shorting out that is cutting off the power to the compress? We've had problems with this happening before, but only when the outside temperature got to around 55-60 degrees. On heat pumps the indoor coil becomes the condenser in the wintertime and if you are not getting enough airflow across the indoor coil it with cause the high-pressure code problem. • Check. Both times, the button needed to be pushed in order to get the units to operate in A/C mode. Is it time to have the HP switch replaced? So sorry, again that I can not give you an answer.
