Is the heat pump cooling itself down? It is a combination heat pump/air conditioner wall unit.


If a unit is in heating mode the outdoor unit is in cooling mode (outside always does opposite of indoor) after a while if there is a build up of ice on outdoor coil unit stops and puts hot gas through outdoor coil to clear it. The indoor fan stops to avoid and heat loss in area served buy unit once this has been done and indoor unit coil is hot again fan will start. This is the correct operation of the unit to save against bust could and reduced efficiency

Wall unit keeps frosting up, will not heat


Clogged air filter or a loose belt between the fan motor and fan wheel will cause a frost up.

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

I have two senville mini split 18000 and they both frost up with in 1 Hr. of use both have been pumped out and recharged


Dear Friend! Before recharging gas.did you check leak testing? If not, again you will same problem.

And some more reasons for frost up:
1. Indoor coil & air filter dust blocked-clean it. 2.Less rpm of indoor fan motor- replace capacitor or motor.
Thanks, it's helpful to you.

Our toshiba ras13 skv a heat pump keeps going to pre def mode and not heating the house


this happens when the outside temp is low, asthe outdoor unit blows cold when in heating (reverse) then the unit goes to pre def to avoid it freezing. You should hear a whoosh this is the heat being blasted to the outdoor unit to defrost it, then the heat has to build up again before the indoor unit fan runs up again and blows heat. Mine does the same every 20 mins or so (its -2 outside) brrrr
