Hello

I have a 4 door dumper fridge it is not cooling.

It is a commercial fridge stainless steel Not that that matters much.

Anyway the complaint is it is not cooling, There is some ice build up on the back of the evaporator.

I have checked the pressures and they seem to be correct.

The compressor is very very hot and also is the condenser (75 degrees C).

So i have checked the relay.. It clicks and there is a blue spark when it starts.

The compressor starts as well. However within a second there is a second spark inside the relay....

I am thinking that the relay is faulty and will need changing

any thoughts please let me know... Relay or capasitor?

But the Compressor is working BUT HOT
