Varnado EH1-020 VH2 blows cold air or wont stay on
Used only mildly for one winter. It only blows cool air when in the High fan mode, and when in the auto mode it only cycles on and off a few seconds at a time, but the air is hot. At $70.00, I should be able to get more than just a season out of this turkey. Any ideas?

THERE IS A LIMIT SWITCH THAT REGULATES HOW LONG THE HEAT STAYS ON SOUNDS LIKE THIS LIMIT SWITCH WHENT BAD MOST ITEMS LIKE THIS HAVE A FACTORY WARRANTY THAT COVERS THIS ISSUE MY RECCOMENDATION IS TO TAKE IT BACK TO WARE YOU BOUGHT IT OR IF YOU LIKE TAKE IT APART WHILE IT IS UNPLUGGED AND LOOK FOR A LITTLE DEVICE THAT BREAKS ONE WIRE TO YOUR HEATER ELEMENT AND TRY TO MATCH IT UP AND REPLACE IT.

Unit needs to be taken apart and washed out , also check to see if motor turns freely by hand , clean base of unit fans / blowers and drain ports / channels . Check outdoor motor to see if bearings are tight or fan overheats and cuts off if so replace outdoor motor .
firstly is the air comming from the outdoor unit cold or warm? if it is cold then the 3way valve is working and it has changed to heating. If it stays warm then it is still in cooling mode. The indoor fan wont come on until the coil temp gets warm enough, ( so it doesnt blow cold air on you straight up). If it is changing into heat mode then the larger of the pipes connected to the outdoor unit should get warm/ hot. If this is not happening then the unit is either out of gas or the compressor is on hollidays and wont come back to work.
The indoor fan will continue to run. When heat pump goes into defrost the outdoor fan stops, the reversing valve switches and the unit is basically working in the cooling mode. In order for you not to feel a blast of cold air in the winter the electric strip heat also comes on so the indoor fan must run while the strip heaters are on.
I have the similar problem with both my Jaguars, one is a 1988 Jaguar XJS, the other is a 1987 Jaguar XJ6, both blow COLD air out some vents while it blows warm air for heat. I heard it had something to do with the cold air blowing as a dehumidifier, I don't know if this is true, but it is really annoying to have both cold and warm air blowing when I need heat in these cold Canadian winters. If you find out please drop this website a note and let us know how you solved it. thanks.
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!
