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.

Air conditioner isn't very cool

There can be a couple of things that could be happening...
The first and easiest thing is to check the air filter. Make sure that it is clean... clean it or replace it. Next check the air vents to make sure that they are open and giving you good air flow...
Also check to make sure that you are not icing up on the indoor coil... ice will tell you that you are low on refrigerant. You also could be low and not be icing over, but you would need to have gauges on the unit to check that.
Finally check and clean the outdoor coil...this also can give you problems if the heat is not being removed from the outdoor unit efficiently...
You may also have a unit that is sized in such a way that it hits the balance point at about 85...that means that your heat gain is equal to the capacity of the unit...I often try to size them for about that here in Northern PA. because wqhen seldom get hotter then that and the unit then is much more effective at removeing humidity at lower temperatures...

Here is one about cleaning the condenser coil and at the bottom of that one are links to others..

Ice formed around the filter area last night. Unit quit cooling.

Ice forming means you have your AC set at a temp that is too low. Of course it cannot remove the heat from the air if no air can pass over the coils. There is very high humidity in the space you are trying to cool ... slow down a little on your cooling process.

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.

DPAC 13009 portable air conditioning problem

Remove your remote control on the unit, follow the manual step by step. First, do the emergency on/off button, then operate the air conditioning using the remote control, follow the procedure of your manual.You may notice a clicking sound of your remote control. The yellow/green color of your emegency on/off button will turn to blue. Do not put it back your remote control on the unit because he may sense the temperature of the vent, and your air conditioning will not stay on, it will shut off every five minutes. Your problem is solve.
