I have noticed my heat pump is freezing up on the outside unit, we have had freezing rain and snow the last 2 days but I have never noticed ice accumulation on the outside of the unit, it also seems like...


In freezing weather the heat pump efficiency drops. The freezing is normal. The equipment has a board and sensor to defrost your heat pump. Now this system can fail but freezing rain and snow get pulled into the unit get pulled into the unit coil and freeze blocking airflow. You can defrost the unit by turning it to cooling. This is what the defrost board does automatically.

My heat pump is frozen up today and it is 60 degrees outside and I have my heat set to 66 degrees. Is this normal?


You post is not clear as to where the freeze-up is occurring. I'm going to assume the outdoor unit is frozen up.
Heat Pumps don't generally freeze up at 60 degrees. If the ice around the unit has an uneven pattern (for example a thick spot around the center or at the very bottom) could indicate a low refrigerant charge. If the ice is even throughout, it may be one of the following:
*Sticking Contactor*.....turn the system off at your thermostat and check to make sure the unit outside shut off. If it doesn't turn off, it is likely to be the contactor.
*Failed Defrost Thermostat*.....if the defrost thermostat fails "open", the system will never go into defrost.
*Failed Defrost Control Board*......this could also prevent the system from going into defrost
*Failed Reversing Valve*........put your system in COOL mode and check to see if it will blow cold air inside approx 16 - 22 degF lower than room temperature.
*Failed/Failing Condensor Fan Motor*.......ensure the condenser fan motor is running during heat and cool modes. The condensor fan motor will not run in OFF/Satisfied Mode or in Defrost Mode.
I hope this helps. Good Luck! :-)

My heat pump will not come on in HEAT or A/C. I thought I might have a simple defrost control board problem, but still no go after replacing the board and the defrost relay. I checked the pressure switch...


Hi; Need more info. How old is the equipment,look on the outside unit data plate it will give the built date usually in the top right corner. Also heat pumps can run with a faulty defrost board. I would check for control voltage at the secondary side of the transformer should be atleast 24 volts ac. Also the test post on the defrost board are for troubleshooting a defrost problem not an operational problem.When the posts are temporarely shorted the condensor will go into a defrost cycle This step will let the tech. know if defrost is operating normally. Also I have seen a reset switch manualy reset but not reinergize the control voltage. Also the outdoor unit has a delay timer that will wait for freon press. to equalize befor letting the unit operate. One more thing do You now if Your tstat is operating normally. One more idea is the defrost sensor if faulty it can leave the condensor in a defrost state of operation. This intern will sometimes go to heat strips because they are used in the defrost cycle to warm up the air conditioning going on durring a defrost cycle. One more thought is does the control contactor have 24 to 27 volts going to it if so replace the contactor. To test this using a voltage meter and touch after waiting 5 min. both sides of the coil. Remember voltage is deadly so ..When in doubt call a qualified tech.I ASSUME NO LIABILITY FOR INJURIES TO YOU OR THE EQUIPMENT BE CAREFULL!!! IF YOU GROUND YOURSELF BETWEEN 230VOLTS THIS BE VERY BAD...alpharome416

My heat is freezing up because it is cold out side,what do I do


Sounds like you having a problem with the defrost board, also check to see if the freeze stat is connected, if not it will not since the coils temp and send a signal to the board to go in defrost and your electric heat strips should kick on if you have them. Depending on what unit you have you be able to which the dip switches to call for defrost at a quicker or longer time depending on the outside temp.

Goodman heat pump wiring


ok Let me see if this helps if not please comment back with the t-stat model and make as well. The Y terminal on the t-stat needs to be connected to the Y terminal on the heat pump board. If this does'nt fix it your thermostat may have something different going on so please send me the model and make of the t-stat. Also if you know does this unit have outside temperature sensing probes, and or an automatic defrost cycle?

Start with the simplest first it,s not fun but it's necessary EVERY TIME. Clean your evaporator and condenser coil, change your air filter. Getting to the evap. coil is often a real headache and a result doesn't get done often. When its clogged as you probably know the refrigerant can't absorb heat at the coil so it tries to absorb heat on the way to the compressor freezing the hot gas line the safety circuits that protect the heat pump compressor from getting liquid refrigerant back to the compressor almost immediately will take the compressor of line (looking somewhat like a defrost cycle). I hope this helps it's a tough repair GL!
