Freezer Fans Not Working

[bhollarattan]

Hi Friends,

Just need help !

Freezer fans are not working. There are 4 semi hermetic compressor. 1 is for freezer and 3 are for cold room. They share common condenser of 7 fans.

1 Fan is working and 2 fan runs for a while and then stops.

The evaporator coil is covered Ice on top half of compressor. So the freezer is not freezing properly. The Temp is showing around -11 C and it has set to -20 C.

I have changed the Relay but no luck.

Also, Suction pressure is around 6 psi and Discharge pressure is very high around 200 psi.

I found Freezer Timer is not energized. But when i replaced it with new Timer and still it is not energized.

I have attached Pics for your reference.

Please send your suggestion friends.
