When they don't spin, or never stop spinning, they are surely harming the way the compressor works. Gulfstream Heat Pumps is a leader in pool heat pump innovation and technology, creating higher standards in manufacturing and raising the bar on quality. The water pressure switch should be adjusted to turn the, heater off when the pump is off. It's about water movement, not just pressure. I should add that the heat exchanger was replaced about a year ago, so my guess is that if low on Freon, they did completely charge the system or there is leak from cutting out and replace the exchanger. The water pressure switch may be incorrectly calibrated. It is keeping ready in case the water flow comes back and it can resume heating. Many features may not work properly without it. Control Board Failure. If your heater is out of warranty, sometimes, its simplycheaper to do it yourself. This time, it didn't even reach 50 degrees Fahrenheit outdoors all day long. Thank you.

The heat pump's controller board is overheating. Failure to heed the following may result in injury or death. Setting the switch to close at too low of a flow can damage the. 2. Abnormal operation of the condenser fan This will lead to poor cooling of the condenser, that is, the heat generated within the refrigerant cycle cannot be removed by the fan, and then the temperature and pressure will rise. In your case, R410A. Failure to heed the following may result in damage to equipment. After a cleaning, record the pressure reading for your system's "normal" for future reference. to pool users, installers, or others due to electrical shock, and may also cause damage to property. I have replaced the Stack sensor thinking that it was the problem. Verify filter and skimmers are clean, backwash if necessary. So, I opened the 3-port valve and adjusted it where the 2 return lines are fully open. The electrical circuit and components on a heat pump will vary in style. P.S. 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). What flow rate do you have going to the heat pump? It is very cold outside. I didn't think about the internal bypass on this unit. Dealer Sales & Service Guide 1- 61 11 Check to make sure you do not have any bypass valve or any valving in incorrect position which is causing flow restriction Check pool filter pressure gauge -Rule of thumb Sand filter low than 25 psi, Cartridge filter lower than 15 psi , Earth Filter lower than 18 psi In Floor cleaning system valves not working properly the pool place thinks it might be putting copper into my pool. If connected, a gas backup heater may start and stop at an incorrect time when set to use a "SCHEDULED" mode. Is the water to temp when the pump shuts off? Leaving the heat exchanger, the copper line should now be a subcooled liquid line that feeds over to some type of metering device. FIX: 1. Fill out a contact form to get a personalized response from our pool heating experts. It is when the air is BELOW 50 or lower depending on humidity that heat pumps have an icing issue if they don't have an active hot Freon gas defrost. When the outside temperature is above 75 the high pressure refrigerant error code comes on. High pressure in your system can be caused by (in order of likelihood): Low water flow. Pull vacuum and recharge. Faulty Capacitor. Use a pool cover. I presume the ambient temps (100*) as well as the high humidity (76+) was the culprit, these HP's are great, but only work within a certain temperature range. 3.6 kWh x 0.15 cents = $0.54. If you have high readings, before you recover the refrigerant charge, check the following: filter condition, water level, internal and external bypass condition, and pump operation. Is there a common thread between the times it does/doesnt work? 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. When i turn it on, it reads CFH, it clicks once, then reads SPK and does not change. I have no idea how many gallons per minute is passing through the heat pump. It could be a header gasket that is causing the leak. Repairs must not be attempted by untrained or unqualified individuals. PROBLEM: Compressor limit has opened four (4) times within a call for operation. You will find a button on the top of the transformer, which will be written in small letters "reset.". Inspect these parts for corrosion, scaling, and/or any electrolysis issues. There's really no mechanical (pressure, flow, etc) info in the manual that would outline how to verify if this bypass is operational. Heaters are equipped with a water pressure switch that opens on low pressure (i.e., pump off or flow restriction). It is refrigerant. $1000. Look for loose connections with the igniter, gas valve, and ignition. Call your dealer for advice. I have a Hayward H350 propane heater with IO code displayed. Restricted airflow over condenser.

In particular, look for kink or rodent damages. Dirty outdoor coil. 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). Over the past week, the heater fired up and heated just fine. Sometimes it may take a bit of time to find the right fit. Inspect & clean pump impeller. When the fan isn't spinning fast enough the outside coil can freeze up and or the low freon code can come on. If no power, replace the board. Okay, Tony, I will ask the same question to you as well. Evaporator coil is dirty. Wait for two minutes for the capacitors to discharge. The error at the primary heat pump must be corrected before the secondary unit will resume operation.
