Check your airflow. grills open, filter clean etc. typically when a unit runs once and won't come back on without a reset it points to a safety switch that is kicking the unit out. By cycling power you are resetting the switch until the next trip. Many times related to lack of airflow.

COMPRESSORS HAVE AN INTERNAL T-STAT TO PROTECT THE WINDINGS ... SOME THING IS CAUSING YOUR COMPRESSOR TO RUN "HOT" THIS WILL KICK "IN & OUT" THE COMPRESSOR DURING COLLING OPERATION AND HEAT MODE (IF IT IS A HEAT-PUMP). 1ST THING TO EASILY CHECK IS THE CONDENSOR "OUT-SIDE" COIL. (CLEN BOTH WHILE YOU ARE AT IT). THESE FANS PULL THE AIR IN AND A BLOW OUT THE COIL .... ALL THE DIRT WILL BE ON THE INSIDE. 2ND THING IS THE FAN ITSEL OVER HEATING AN TURNING "OFF" ON ITS OWN "BUILT-IN POTECTION T-STAT". THIS WILL GIVE YOU THE IRRATIC OPERATION YOU ARE DESCRIBEING. I TEND TO THINK IT IS YOUR FAN MOTOR ... EASY TEST. TURN "OFF" EVERYTHING BUT THE FAN. SET IT FOR MANUAL "RUN ALL THE TIME" POSITION. THE FAN SHOULD NOT KICK OFF !!! IF IT DOES YOU FOUND THE PROBLEM. IF IT DOES TURN OFF IT CAN BE A WEAK CAPACITOR. UNITS VARY ON WETHER THE CAPACITOR IS FOR COMPRESSOR/FAN OR HAS A SEPERATE CAPACITOR FOR EACH. CAPACITORS ARE NOT EXPENSIVE. HOPE THAT CAN NARROW YOUR PROBLEM DOWN

Hello Tom , I'm sure i can help you with this.... I work on these units everyday. unfortuneately im not there to put my hands on it but i will explain as clearly as possible. The most common problem I tend to find with these units is that the control board and indoor fan motor tends to go bad in these quite often. If you put the unit in A/C MODE and/or Fan mode and set it to high if it will not speed up from low , then your problem could be in a couple different places. 1st. The bearings in the fan motor could be wearing down , 2nd The Control board could be bad in that its not telling the fan motor to speed up. And when you tell me that the compressor doesnt run in that mode at any given time..... which the electric heat and heat pump itself works together so that when the load is really tough that the heat pump doesnt over work and in general saves life on your compressor. Solution is this. Take your indoor fan motor off and and drill out the rivits and it pulls apart easy, and replace the bearings and grease them. ALIGNMENT OF THE FAN IS A MUST. doesnt cost much at all the fix this. Just a little time and bearings Replace the Board in the control box This my friend will definetly solve your problem. These problems i see everyday with these same units.

I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.

Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!

Hi, as you know the thermostat controls the unit. Here's what you need to do first. Go to your thermostat on the wall, pull off the cover. You are looking for the main control wires that come in from the back to connect to the screw terminals. Don't be afraid of shock as these are millivolt wiring connections.You say the fan shuts off but the compressor keeps running causing it to ice up. You need to get a screw driver and disconnect the wires from this stat. This should cause the compressor, fan, and all to shut down. If it does, you know that your thermostat is faulty and you will need to make your self a drawing on the wire connections, remove the stat, and you can get a new one at a RV sales and parts house.Find your breaker box where your main wiring comes in and shut off the a/c breaker if you like. Now, if the compressor keeps running after you disconnect it from the thermostat, then somewhere from the stat to the controls on the top have a hot wire that is touching somewhere causing the compressor to be energized all of the time. If you can go up top and find where this thermostat wire comes in, look it over good to see if the red is touching the yellow wire some where. I believe you just have a faulty stat at this point. Do what I asked on the stat, disconnect it completely, and we will go from there. You can get back to me by leaving a comment under my user name. Please let me know and we will take care of this problem.
