Question about Coldtech 40 cu. ft. / 1133 liter Commercial Freezer J4SFF-40B
Unit runs ok until defrost is on, when it comes out of defrost the unit wants to start but can't. Internal o.L tripps and does this several times.
Run amps are 9.2 The start amps at this point are 27.6amp on a 20 amp breaker. The start cap mf are 188 to 277. and reads 302 mf.
This is 115v unit and total amp on lable say 12.9 amps.
LRA on lable to comp. is 74.0.
I have lowered the charge a bit to keep head pressure down in hopes to keep unit running. This has been an on going problem since this unit was new. Any solution to solve this. Thanks for the help. Don
If the start relay and cap are ok then I'd say it's time for a new compressor. Have you tried running the compressor directly with a direct start circuit? cheers
