The reason is simple: TFPC (Trouble Free Pool Care) is a methodology, not a product that you must purchase. No Airflow Step 3. Hello , This is an inactive thread. Water has always been in tip top shape. Hello. 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). A dirty filter can cause low pressure and as a result, cause the heaters pressure switch to turn OFF. Possible Cause: 1. One of the most common problems with pool heaters is it failing to ignite. Many features may not work properly without it. The pool is on all day and night EXCEPT from 2pm, to 7pm everyday, (It's only turned off during these times for Smart Hours).

Check to see if the heater has proper ventilation and no blockages.'. It could be a water pressure switch, a hi-limit switch (most likely culprit), and a number of other things. Heat pumps have horrible hydraulic design. Electric line is fine. Check for correct incoming power at fan relay- 120V or 240V and at fan motor. Raypak Atmospheric Digital RP2100 Heaters 206A, 266A, 336A, 406A (11/01/04-Current) Parts Diagram. Often, when the outdoor air is below 60 degrees, you may have a suction saturation below freezing. Advice? Maybe you wanted to People get swimming pools for a few reasons. Reply Report G GettingThere New member Mar 17, 2020 3 Sebastian, FL Any additional thoughts? Did you ever get this resolved? The refrigerant system's high-pressure switch is showing as open. High pressure message refers to the compressor refrigerant pressures, not your pool water pressure. . In your case, R410A. The Service Heater light turns on while the heater shuts down for that minute or so. Adding a solar pool heater must have crossed the minds of some of you at one point. You can test this by buying another sensor and swapping it in. The real-time clock controller indicates a low battery condition. Faulty Fan Motor. Ill keep you poste. Is the pilot lighting?

Then it sounds like you need to have a tech come to take a look at it. 840p 2-Way NPT Ends 9365P 9365PH 8265P 365P 840P WCCW-HR WCME-HR WCCW65 There will be some form of user controls that report back to a board that takes this input and a reading from a water temperature sensor to determine if the heater should run or not. Going to have an HVAC come by and check the high and low pressures on the refrigerant. Caution: High voltage checks. heater. Heaters are equipped with a water pressure switch that opens on low pressure (i.e., pump off or flow restriction).

Make sure to keep your valves open as to not prevent the water flow. Inspect the wirings carefully. Hi Bob, The condenser water loop is open to the atmosphere in the chiller. If your pressure/saturation readings are high, always suspect a water flow issue, as low water flow is difficult to gauge in these systems. Any other suggestions? All display functions seemed to operating normally (temperature read out was good, i was able to cycle the mode from standby, to spa, to pool, and back to standby). There are multiple ways to diagnose the pressure switch fault. $800. When the head pressure builds too high, the high pressure switch will open causing the heat pump to shut off immediately. Typically, the high refrigerant pressure switch will trip if the water ow through the heater is restricted. The condensation should disappear. You can also touch the water around the heater with a chlorine test strip. Check for correct incoming power at fan relay- 120V or 240V and at fan motor. A refrigerant is a chemical mixture that allows heat exchange to occur. Ensure thepump basket and lid are in good conditions.
