Hear pump keeps running constantly, why won't it shut off?

if some units detect ice they will leave the fan running in an attempt to defrost the coils. If it's the outside coils and it's warm enough inside, try running the air conditioning for a few minutes, that will put hot coolant through the coils and could melt the ice for you.

I have a Mitsubishi heat pump that runs well but the outdoor unit does not defrost what could be the problem.

Why does my heat pump ice up in Winter?
Heat pumps naturally ice-up in the winter. It is normal for the entire coil to be covered in a white frost and even light ice, during cold weather conditions. However, it is bad for the entire unit to be encased in ice. This indicates ductless heat pump problems which should be addressed quickly to save energy and avoid serious damage to your ductless unit. These systems should periodically go into a defrost cycle. This keeps the unit running efficiently. If the coils are blocked by ice, proper heat transfer between the coil and the outside air will not occur.
How does the defrost mode work?
When the mini split heat pump goes into defrost, the reversing valve inside of the outdoor unit is energized, switching the system from heat to the air conditioning mode. The outdoor coil becomes the hot, the indoor coil becomes cold, and both - the outdoor and indoor fans shut off. This allows the outdoor coil to melt accumulated ice. When the built-in micro-computer analyzes that all ice have been melted, the heat pump heating system goes back to heating mode.
sanyo-mini-split-defrost.pngA cloud of water vapor may be seen rising over the outdoor unit and a "whoosh" sound can be heard as the refrigerant reverses direction. The entire process usually takes up to 10 minutes (depending on conditions).
How often does the system goes into defrost mode?
Ductless mini-split heat pumps have different ways of determining when to go into defrost. The built-in microcomputer determines outdoor temperature, refrigerant pressures, and several other factors. In colder temperatures the system will go into defrost more often than in warmer.
If a ductless mini split heat pump is severely iced-up in the winter it is possible that it isn't defrosting (though there could be many other causes). Let the manufacturer certified technician check your system

I am not having a problem with my portable air conditioner unit but I do have a question about the unit having a heating fan. What would a heating fan be used for in a Air Condtiioning unit with...

To defrost the heat exchanger in between cooling cycles. As it air conditions, it pulls moisture out of the air, and causes a layer of frost to form on the heat exchanger. Some units just let this frost melt off. But if it doesn't completely melt, it can start to form an unmeltable glacier. Since your unit in a dehumidifier model, it probably relies on the heater fan to ensure that you don't get an ice-up on the exchanger.

I have a digital Total Line thermostat that has a blue, white, yellow, red and green wire. Where do I attach these wires to the Model 44300A unit?

Normally Red to R (24v coming to stat) White to W (Heat) Green to G (Blower)
Yellow to Y (Air conditioning) Blue to C (common)
This is assuming you have gas heat and central air conditioning. If you have a heat pump blue would be for that. If you have a volt meter, check voltage between red and blue with furnace turned on. It will be 24 volts approx. if blue is common.

New heat pump system freezing, questioning wiring.

W1 and E on stat need tied together. When W1 comes on wire where all heat elements come on. On the outside unit defrost board set the 45-60-90 to 45 and see if that takes care of the frost problem.

Blue ice from ice maker

I have this problem too. Seems to be a couple of blue paper washers in the unit that the water filters through and they break up. Ive had this issue go on for more than a year now with Liebherr trying over and over not to claim responsibility. Ive sent them the blue washers and photos and all to get analyzed and they simply do not call me back. Their service center didnt even know there were 2 blue washers in the unit. Seems to be a mess. In any case I still have a very large amount of blue paper dust in my ice and its unuseable. Any solutions?

GE ice maker is getting hot

You need to remove the ice maker the function that heats the lower element should last only a few seconds so I believe the ice maker will need to be rebuilt or replaced. Sea Breeze

Ice maker part WR60x0202

Your part number is for and auger motor. I believe the "pump" you are talking about is the water valve part#-WR57X10023 if the icemaker doesn't send voltage to the valve then it would need to be replaced part#-WR30X0327
