Answers :

The coil probably needs to be pulled and cleaned with a power washer. Usually what happens is the coil becomes dirty over time and when the filter starts to get dirty as well, it will cause the unit to free up. Also it could also be a little low on refrigerant and when the temps change, it can cause the coil to freeze up. But I bet it is in need of a good tune up and coil cleaning.

Hi there, I have two Fujitsu DC Inverter split units to heat my flat (england). The temperatures have dropped significantly -2 and below. This causes the outlet pipes to freeze up and when the units are on defrost the excess water gushes out of all other joints in the units. This causes two problems - the units are wall mounted one on top of the other, so the top unit freezes the bottom unit. The second problem is the bottom unit 'dumps' in on the floor of the area which when defrosted s
