Defrost Cycle Problems

I live in North Fl;orida and I have a 5 year old WeatherKing Air to Air Heat Pump MODEL 10PJA4201 which works Great, Good Cold Air in summer, Good Heat in winter, Until it gets really Cold out side, then it hangs up in the Defrost cycle the out door condensing unit only humms and the fan doesn't rum. The indoor Air handler and heat strips runs and recycles the indoor air without any heat from the Heat Pump. I got up one night and monitored it and the unit remained hung up in the Defrost Cycle for 3 hours, until I bumped the thermostat down enough to shut off everything indoors and out doors, after waiting approx 2 minutes i bumped thermostat back up calling for heat, everything came on and ran fine the rest of the day, until the next Cold night and it happened again, What might the problem be?

It is either the defrost thermostat or timer in the main board, best to replace both, and have charge checked.

BUZZING NOISE FROM MY HEAT PUMP


Take a look at this YouTube page that explains with good videos what are some of the common problems with heat pump noise. The one that seems dominant is the defrost cycle a heat pump goes thru when it melts ice off the evaporative coils. In defrost cycle, The compressor runs but the cooling fan does not, so you will hear a loud buzzing sound and the unit sounds like it is stalled...because only the compressor is running to generate heat to melt coil ice.

I have a 5 year old heat pump (electric) Home is 5 years old and is very energy efficient with 6 inch outside walls. Do I have a problem as the air will run for 5 minutes and shut off for 5 minutes and...


One thing you might check is to make sure there is not cold air blowing across the thermostat from one of the vents. I've seen this many times make the thermostat short cycle.

Some less expensive thermostats may be programmed to short cycle. If you have instructions available for the thermostat, try to find information or the "heat anticipator". It may have an adjustable setting.

Fujitsu heatpump 13 years old is not heating room as it used to.filters are clean.i have gauges and would like to know what pressures are good and what pressures indicate low refrigerant or worn...


The refrigerant and compressor are related in cooling the room.As for heating problem the thermostat needs to be checked.
if you're used to a certain temperature of air and your heat pump is producing much cooler air, take the following steps. (Note that a heat pump may go into a defrost mode to prevent icing. When this happens, it can temporarily output cold air. Also be aware that the heat pump will have to work harder to produce heat.)

1) First be sure the thermostat is set properly. Try raising the set temperature 5 degrees F. and waiting a few minutes.

2) Be sure the room-heating registers are open.

3) Check the heat pump filter. If it's dirty, change it.

4) Be sure the auxiliary heating elements are working . 

5) Clean the coils of the outdoor condensing unit.
If still the same problem then thermostat needs to be checked and replaced.
Thanks.

I have a heat pump and it freeze up


If you are referring to the outside unit freezing up, the issue is in the defrost cycle. The defrost cycle works something like this: The unit reverses the flow of freon causing the inside coil to blow cold air into the conditioned space and the outside coil is now working like an a/c unit, it gets warm to melt the frost/ice. The inside unit electric heat strips come on so you do not notice the cold air being blown in. The fan on the outside unit stops running to allow the coil to get good and warm.
Now the unit should go into the defrost cycle every 90 minutes or so. It should not terminate the cycle untill the coil is clear of frost. There is an "Klixon" type termostat that measures the temperature of the outside coil. This is most likely the problem. It is prematurely terminating the defrost cycle. I'd start there first.

Hope this helps, Let me know if I can be of any further help.

Defrost Cycle Problems with Heat Pump


It's a defrost board issue. The timer on the board or something similar is hanging up. Unfortunately the solution is to replace the board. By lowering the temp. on the T-stat you are resetting the timer on the board. As you see that only works until the next cycle.

Tempstar heat pump: want to bypass defrost thermostat


Don't attempt to bypass defrost mode. If it's cold enough to use as a heat pump, it's cold enough to need the defrost cycle.

It sounds like a sensor issue, although it may be the controller board.

Unless you know how to work on equipment like this, I urge you to get a professional to service the unit for you.
