That will tell you if the switch is Bad or Doing its job as designed! In heat mode, the indoor coil becomes the condenser and that is where the high pressure (gas to liquid) exists. Is the coil a Goodman coil? present at the heat pump/defrost control. Check valve inoperative. "Is this the cause of the lockout issue ?". There are multiple possibilities but they are easily worked through if one know's what they are doing. I have a Carrier Puron R-410A heat pump. But heat pumps also have one huge benefit that furnaces lack: Heat pumps help to regulate the heating and cooling of a house by redirecting energy from the air outside the house to regulate the air temperature inside the house. It would be nice if any system you choose featured a "networkable" thermostat so you can monitor conditions from your phone/computer....of course that would require internet access at cabin... Best of luck. Compressor kicks on and runs for 3-4 minutes and the high pressure trips. 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. Good luck. I'm not sure if they're liable or how we would even prove anything. He then verified that the AC was working correctly. If you can't get a straight answer from the service companies, call the local Goodman distributor and ask them - they are usually your best source of information (don't waste your time calling Goodman - you'll just get a kid on the line with a brochure who will refer you to a dealer).

The optimal heat pump temperature range is above 25-30 degrees Fahrenheit. 1st you need to find out what the actual pressure is. Make sure the fan runs with nothing blocking the air flow. It keeps triggering the high-pressure cut-off on the outdoor unit. If this switch needs resetting on a heat pump, it means the head pressure or the high-pressure side of the heat pump is exceeding maximum pressure. That's a must as they use communicating controls. 1.03 is very high. We used the AC on only two days during the summer and everything seemed to work fine. currently its Horizontal right, return > Air blower > Coil > Supply. I can reset the trips, and the unit will run a few times, but eventually will lock itself out again. With no abnormal pressure conditions it … Close to max. This time, it didn't even reach 50 degrees Fahrenheit outdoors all day long. The alarm/fault clears after the issue is corrected. I would worry about it not keeping up with harsh cold and if you loose power, freezing of water lines. First thing I need to clarify is if the blower and the coil need to be swapped out. That's all I know/understand about that. Not sure where the indoor col is. There is a new model now, I think. Earlier today we ran a test of sorts by cranking the heat up and letting the unit run for a full hour. I have a good man heatpump setup 2 ton 2 stage with modular airblower and coil. This takes hot water from boiler and loops it through air handler and uses that warm air to heat rooms by duct work. As an example, Trane includes a pressure curve chart with many heat pump condensing units. In November, we started using the heat and it seemed to work fine. This means that you should therefore use only high pressure switches that are rated with the maximum working pressure specified by the manufacturer for the specific heat pump. I'm not sure if the heat was functioning correctly at all but the tech that came and serviced the geothermal unit prior to us closing on the house said that everything was functioning normally (after repairing the AC part by turning the water up). As a rough guide to the pressure ranges that occur with the various refrigerants, consider the pressures at a condensing temperature of 60°C. Make sure you have correct underlayment or floor substrate. Do you have any problems in cool mode? Changed the filters in the main unit and just found the coil. I needed one but my area was about 1200 square feet and three separate zones with a master and two slave thermostats. Traditionally, in-floor radiant heat (electric mats) will DOUBLE or even TRIPLE the cost of tile install. Propane can be used in conjunction with High Efficiency "on demand" boiler. The system itself is not expensive, it was roughly $2300 for 1200 square feet or close to it. 3. I thought installs were always warrantied/guaranteed? Surprised you don’t have a warning for that. Code 33 – Limit Circuit Fault AND high heat only is active Code 45 – Control Circuitry Lockout Code 41 – Blower Motor Fault ((-A) models only) ... 84 Hi Capacity Compressor Lockout HIGH PRESSURE LOCKOUT 4 HOURS 85 Low Contactor Open LOW CONTACTOR OPEN 86 … I verified this by walking through the procedures and codes on the diagnostic panel inside the condensor. I'll give it a week and see if the problem comes back I'll call a pro.
