The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

Hi,
The power went off and then back on again... on the startup it shows you that your a set up for a 2 speed heat pump by showing you the H2 code.
Now you will have to just reprogram the t-stat again as you would if it was new...

The good news is that there probably is nothing seriously wrong...

It is important that the connections from the outdoor unit is wired to align correctly with the indoor unit where the main control panel is located . The outdoor unit compressor is switched on from the processor here and so it is marked in detail to connect the wires.
Now the if the indoor unit is not powering then there is fault in the main control panel and you need to get help as this is a new unit and warranty should not be compromised.
It is possible that the new unit has a damaged control panel or power and so does not power. take help.

There are many possible reasons why it happens that way. Basically, when the unit have reached the desired room temparature,compressor stops as will as the condenser fan.Please try to set your thermostat at its coldest setting, if the fan at the outside condenser still stops, consider replacing your thermostat, it migth be defective.

Your 042 is rated 3 1/2 tons

The number you are referring to as your 'model number' is a number I don't recognize; maybe it's the SN or something - I don't know.
But that other number - "38CKC042" -------'is' --- your model number and the size of your AC is 42,000 Btu or 3.5 tons.

Hi,
That unit is approx. a 10 SEER unit when hooked with most coils...

Seems you have a leak & lost your Freon Coolant! Have someone add some Freon with leak detector & look for a oiley color, usually purple die or red die! If their is any Freion in your system you should show some pressure readings!

What woud be your concern? you can buy a diffrent unit from another dealer. Trane and Satndard are just as good. its the quality of the install and how well they back them up that counts .. You shold get 5 years on tne compressor .. Hopethis helps Jon

could be the run cap but also could be motor windings are getting weak. I would replace both the cap and the fan motor for preventive reasons.

James, a 38 ck unit would normally have a piston. It would be located behind the brass nut that connects the small tubing to the indoor coil. If a txv was installed you should actually be able to see that the piston was removed. l

No reset,only repair for the broken part.

If this unit is new more than likely the condesate drain line does not have a deep U shaped "trap"in it. This allows the negative air pressure inside the unit to draw air up thru the drain line holding the water inside the cabinet until the fan shuts off, then the water can drop out of the unit everywhere.

If the system has been in foe some time and has the proper "trap" the drain line could be plugged any where there is a turn in the pipe. It is a messy clean out but it can be done by cutting the straight PVC pipe, right after the screw in fitting and the 90. This will allow you to unscrew the fitting at the unit and clean it out. Sometime there is a gel like clog that grows at this point. Then you can take a wire or compressed air to clean out the rest of the line to the outlet. Next pour hot water thru the PVC and see how it comes out the end. Worst case you will need to pour a solution of hot water and white vinegar to remove any build up.

Hi,
The condenser coil is plugged and the unit is cutting out on high pressure....
Here is a tip that I wrote about how to clean your condenser

just patch it or sit it on a piece of metal

There usually isnt a reset however there always is a auxillary limit and those are most always automatic reset but it is located on the blower housing. Whats going on is the blower trying to come on? If it seems like its not trying to come on find out where the wire connects to the circuit board take it off and check voltage you should have 120V. Let me know what you find ok.

Well it could be a few things. 1. bad contacor/relay. or the motor is bad and needs replacement also could be bad capisitor
