We had some problems over the winter with one of heat pumps (6-ton Trane GEHE) locking out on high pressure, the fan would continue to run and compressore would shut down, particularly when OA temps dropped below -10F. The unit is only 4 years old. A geothermal power plant operating on high pressure geothermal fluid includes a primary separator for separating the geothermal fluid into two channels, one containing high pressure steam and the other containing high pressure liquid. undercharged refrigerant? The LED indicators are the following: - 1st 3 minutes - ON, OFF, Flash = Anti short cicle - 2nd 3 minutes - On, OFF, ON = Compressor is on - 3rd 3 minutes - On, Flash, Flash = Soft Lockout (high pressure) I After the unit lockout indicator light goes out, turn the system back on to the desired MODE. If my memory serves, the refrigerant circuit more or less balances itself out around the source/sink temps and resulting pressures (these heat pumps have limited staging I assume). Though lockout mode errors and resets do vary from manufacturer to manufacturer, most use a simple reset procedure that involves turning power off to the furnace for thirty seconds or longer and turning it back. Carrier will not provide any service manuals for their equipment and I hate to call their servicemen for something I could handle myself. Lockout – when locked out, the blower will operate continuously in “G” speed setting, and PSC blower motor output will remain on. when there is no enough refrigerant, compressor is going to its peaks trying to reach capacity.

I had a similar problem on a water to air HP. The system uses a compression cycle, much like your refrigerator, to collect the earth's energy supplied by And when it comes to functional prototypes, 3D printing is rewriting the rules of what’s possible. Carrier Infinity Error code: 84 High Pressure Lockout For 4 Hours. The earth coupled heat exchanger (geothermal loop) supplies the source energy for heating and absorbs the discharged energy from cooling. Fix for low pressure in a geothermal ground loop - YouTube. In the old days we would take the cover off the relay (or contacts) and use a clean dollar bill to burnish the contacts, Smith G8-3 with EZ Gas @ 90,000 BTU, Single pipe steam. Probably hi/lo mixed air temps. Share. Contractor's Assistant: How old is the appliance? Count the number of flashes between the ten second pause and compare to fault code chart below.
