Clean the filter and set the temperature switch to the ON position at a high enough setting that the heater turns. 4. Probably low refrigerant or a compressor problem. You can still check the superheat and, if possible, subcool. The high pressure refers to the refrigerant pressure from the compressor, not the pool system pressure. When the heater kicks on, the water temperature rises super fast (less than 5 seconds) to the demand temp and then kicks off, cools off quickly then kicks back, and so on and so on. Repair suction air leaks, grease pump lid o-ring. Hope it's as simple of a fix for you! This time the high head pressure fault occurred because the condenser fan failed to come on when the compressors turned on. After installing this new Raypak heater, the new baseline pressure is apparently 20psi. When measuring PPM, we have to keep in mind that it doesnt indicate the size of the leak or leak rate, but it does help us pinpoint the leak location. So I thought that was causing the problem. Leak detectors come in many varieties, including heated-diode, ultrasonic, and infrared; each type has unique maintenance needs. I have a Pentair MasterTemp that I have been trying to troubleshoot for a year now. The pilot was lit, but the heater wouldnt fire. The owner of Peregrine was a buddy of mine. Thank you. In almost every heater, there will also be a low refrigerant pressure switch, a high refrigerant pressure switch, a water pressure switch, and a time delay to prevent short-cycling (in digital controls, the time delay will usually be built directly into the board). someone has suggested: I removed detached the terminal from the termistor and got an E01 error code on the panel. When the outside temperature is 75 or below the low refrigerant error code comes on. Does the display look as it should while it is starting up? Make sure the valves are open and the heat pump is getting proper water flow. LOW REFRIG Alarm:Refrigerant low pressure switch is open. 3. I have a WF unit with an ECM blower. I believe now it may be my thermostat. Was told maybe the control board was bad ?,any thoughts. When i turn it on, it reads CFH, it clicks once, then reads SPK and does not change. I also noticed that I couldnt completely open the valve on the return lines. It's about water movement, not just pressure. Do I have to take it apart to check the heat exchanger ? These special sensors monitor and detect changes in water flow. Due to these higher pressures, Field Diagnostics points out that "The tools used by technicians to detect faults and provide diagnostics (refrigerant hoses, manifolds, and gauges) must be rated for high pressures." Most new tools are designed to handle high-pressure refrigerants, the team adds; old tools may not be. We are a registered 501(c)3 non-profit that is funded by user donations.

Place heat pump in heating mode and perform the following troubleshooting. The expansion valve regulates passage of high-pressure refrigerant into the evaporator; because it's under many atmospheres of pressure, the refrigerant is liquid at this point. Is there a common thread between the times it does/doesnt work? I only found 1 small stone stuck inside where the bypass is. Hello , This is an inactive thread. If so. The igniter has a bit of carbon build up but came off with my finger. What should I be looking for? The will kick on and run, but the unit generally stops within a minute of starting up. Heating air causes the RELATIVE humidity percentage to decrease, but it does not change the overall moisture content in grains of moisture per lb of air. This review is the subjective opinion of a Tripadvisor member and not of Tripadvisor LLC. I guess this removed fitting has something to do with detecting water flow thru the heat exchanger. Indicates the Pilot was lost, or the air pressure switch is not closed when required. Failure to heed the following may result in injury or death.
