Fan stops,but unit keeps running

i'm not familiar with your specific unit but ..sounds like an electronic gas value has gone bad or has a bad connection when that happened to my friend it wasn't that expensive to have it fixed .. BYW it acted like this for a while then stopped working completely

Sounds like a bad motor module.

Should like your unit is working fine unless this is constantly happening. If this is a constant thing then condenser coil if dirty,check thermostat setting

Check the blower motor capicator. It should be mounted close to the motor with 2 wires to it (brown,brown/white).
Turn the blower on the thermostat and spin the squirrel cage by hand and see if it runs after by itself. If it does then definitely the capicator is bad .If it still doesn't run then check to see if there is voltage going to motor.
If thermostat is calling for fan and there is voltage present at the motor terminal then the motor is bad

Hi; I need more info. Do You mean the outdoor unit is stoping and starting while running in a call for heat by the tstat. When heat pumps run if the temperature out side reaches low enough the outside unit will go into a defrost cycle to remove any build up of frost or ice. If the outdoor unit has a dirty coil or a low freon issue this also can trick the unit into a premature defrost cycle. Now here is another scenerio.If Your ac is running in the cool mode and stops prematurly there could be several problems. Low freon level, faulty fan motor causing the compressor to go into a freon bypass mode wich sounds very spewy. Please tell me if you are in heat mode.. Also how old is the unit. Sometimes a severly worn control contactor can disallow all the needed voltage to cross over to Your fan motor and compressor. Watch unit while its acting up... Also when unit goes into a sceduled defrost the fan will stop this is normal and will restart when the unit comes out off defrost You will here this big swoosh sound. Thats the freon being redirected back into the heating path.Let me know...alpharome416

yes the fan will shut down during the defrost cycle. But the fan only shuts down during this cycle....other than defrost the outdoor fan motor should be running during a call for heat.

be aware that not repairing this asap that you are causing yourself more problems First I would change out the fan capacitor and see if this could be the problem. Secondly if the capacitor isn,t the problem change out the motor . By continuing to allow the system to cycle like this the compressor will take a dive on you costing more . Good Luck

Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

It sounds like your defrost board failed. You will need a tech to replace it. With that model it may have a parts warranty but you pay labor(?)

Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!
