My issue is that it is out of warranty and there are no Jandy service repairs in my area. *Based on an electric resistance heated pool, which costs $1,000 per year at an electric cost of $.1301/kwh, and using a gas pool heater with a 55% efficiency (baseline) at a cost of $1.09/therm. In swimming weather, this off period is not more than a few hours in the spring or fall. A seasonal average COP of 5.0 was used to determine heat pump savings. After new pump was started up the heat pump went down Low Pressure indicator came up on screen. Pool And Spa Repair Jandy heatpump fault: "High Ref Pressure". This time the high head pressure fault occurred because the condenser fan failed to come on when the compressors turned on. If your heater is undersized, it will have problems heating your pool up. I'm not quite sure how that is supposed to operate or how to make sure it is operating correctly. TEMPERATURE DISPLAY The temperature display indicates water temperature in the inlet of the heater. Low ambient air temperature. If the refrigerant flows in a different direction, it causes a switch in the function of the indoor and outdoor coils, and it changes whether heat leaves or enters your home. With water flowing, check resistance of water pressure switch, if open, replace switch. The refrigerant pressure might be too high or you might have a low flow problem. Possible Cause: 1. Do not exceed the maximum flow rate for the model. Inspect your heat exchanger for chemical or sanitizer damage. The water pressure switch may be incorrectly calibrated. If connected, a gas backup heater may start and stop at an incorrect time when set to use a "SCHEDULED" mode. Faulty Compressor. If code reappears, replace board as memory has failed. 7.

Deactivate heat pump at power disconnect. The control will sense this fault condition and shut off the compressor until the switch re-closes. Have you checked the circuit feeding the heater to make sure it is providing the proper voltage? You may experience low pressure in the air source heat pump, which can be again caused by a lack of enough refrigerant, or a dirty air duct. It calls for heat, heat starts for maybe 5-10 seconds, then stops, temp raises rapidly to 124 then slowly back down to 75 and cycles again doing the same thing over and over again. Including recorded tech training, interviews, diagnostics and general conversations about the trade. Clean entire filtering system and or replace filter element. FIX: Low refrigerant charge. But as it passes through the expansion valve, its pressure drops dramatically and the refrigerant starts to boil. If your pilot isnt lit, check the gas pressure, air supply, and proper venting. LOW REFRIG Alarm:Refrigerant low pressure switch is open. Make the sure the breaker has not tripped. Confirm a smart bus external controller is being used.

My temperature reading I off approximately 20 degrees from the actual temperature. NOTICE Failure to heed the following may result in damage to equipment. In order to take heat out of the air, the refrigerant inside the heat pump's evaporator tubes must be about 10 to 15F COLDER THAN THE AIR so at about 42 to almost 50F (5C) air temperature the heat pumps outside coil is approaching 32F (FREEZING-0C) and any moisture in the air will begin to FREEZE on the coil and ice it up.Icing clogs the small fins, insulates the tubes and stops air flow all of which severely reduce the efficiency. Monitor your PSI reading on your filters pressure gauge. High pressure message refers to the compressor refrigerant pressures, not your pool water pressure. Is there a common thread between the times it does/doesnt work? Leak stopped. That is what created the Grand Canyon. Low Freon pressure. Honestly, this is a very common occurrence.

Is the heater flashing any error codes or making any off noises? Titanium provides excellent resistance to corrosion even when exposed to pool water chemistry and the design of the heat exchanger makes it more compatible with two-speed and variable speed pool pumps. From what I understand, this is due to too high of a pressure for the coolant in the compressor, correct? Make sure external water bypass around heat pump is closed. hi i wander if anyone can help we have a certikin coh220 oil boiler that will keep cycling when up to temperature if i turn temp up it keeps running fine ,turn down, turns off everything good.

The igniter has a bit of carbon build up but came off with my finger. Its a good idea to approach leak detection with a plan, including starting high on the coil and moving down (because refrigerant is heavier than air and may set off the leak detector below the actual leak). For operation, heaters require a minimum GPM flow. Air conditioner unit is over capacity. Failure to heed the following will result in injury or death. Check Alarm Status on Control Board for LOW REFRIG Alarm. A qualified technician should replace the defrost sensor. This heat gets passed off into the water through the heat exchanger inside the pool heater. Compressor contactor is stuck open.
