The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions.
The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator coil, warming it. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions. The condensor coil may get clogged with dirt and lint, the evaporator may get clogged with ice build up, or the fan may quit working due to bad bearings, need for lubrication, or burn out. The defrost timer has an internal motor and contacts which may quit working, some have a way to manualy turn it to switch its mode in case it quits working.
Good day, When the thermostat is turned on, the fan and compressor should come on and start at the same time. If the compressor continues to run and the fan doesn't, then the fan motor or the wiring to it are suspect.
Quote (The fan motor is o.k ). I doen't know how you tested it, but it still remains suspect, since the thermostat sends power to both of them at the same time.
The ER-FF problem that you have is: ERROR -FAN FREEZER so it means that you have a problem with maybe the fan motor or if it's a bottom mount freezer maybe ice built up on the fan motor so it's blockin the fan motor.
Hope i helped u a little bit ! :)
Usually the compressor runs pretty warm anyway. However if you think it's too hot I would start with the condenser coils located either under the unit or on occasion they are located on the back. The air flow across these coils as well as the airflow around the compressor must be maintained. I forgot to ask if the condenser fan is running. Check and make sure that the Fan is running and the air flow is good. Also, When you transported the unit did you move it standing vertically like it normally stands or did you lay it on its side. If you transported the unit on its side you must wait a minimum of 24 to 48 hours prior to start up or the unit could be ruined permanently. The refrigerant has to be utilized through the compressor as a gas. If the unit is on its side liquid refrigerant could be introduced into the compressor and can cause permanent damage. If this is the case I recommend that you turn the unit off at once and wait the 36 hours for the Refrigerant to settle then try it again. This transportation rule applies for any appliance That uses refrigerant, Air Conditioners etc. These units are not that hard to diagnose. The only other item that is usually a problem is the defrost timer. It is not very expensive and can also cause some of the same symptoms that you are eluding to. The defrost timer allows the freezer to periodically shut down to prevent the buildup of frost or ice on he evaporator coils and on the inside the unit. If it is defective, then the unit will either run all the time and cause the evaporator coils to freeze up or will not allow the compressor to switch on and it will not freeze like it should.
sounds like an issue witrh the microprocessor to me as well, although you tried bypassing it it still didnt work its quite possible that the fan aand compressor are runnig on different voltagfe the 110v , new energy effient compressors are starting to run w/ 220, an inverter built into the circuit board could be steppin up power,
