Re: fridge wiring diagrams
FF 614/01 SYSTEM 600 TR922902205 R12 stat friend fitted was a ranco vt9r original stat was a k59 L2545 im now thinking there may be a defrost timer hidden somwear ❓
Re: fridge wiring diagrams
Hi
looks like he as wired it incorrectly,neutral should come from the compressor live so the heater would have 2 live supplies until the compressor switched off and then the neutral would feed from the compressor windings to the heater.
and thats the basis of a defrost heaters power supply

Re: fridge wiring diagrams
weird thing is stats were swopped wire for wire no changes were made to wiring but heater seems to run if compressor is on or not even when we disconnected a wire off stat we thought ran the heater when compressor shuts down. can definatley feal the heater working. got a chap comming tommorow to check gas levels and compressor but im unsure on what stat this fridge should have as we just used what we could find in the shop to get it running again 😉

Re: fridge wiring diagrams
john from A.C.R.E checked fridge again and compressor is gone. anybody know where to get a new one ? ( not fridge just compressor )
and can a r134a compressor work ok on a r12 system?Re: fridge wiring diagrams
Hi
Yes a R134a will run on a R12 system but to be honest you would be better off fitting a R600A compressor far easier,more efficient and quieter.
dependant on the size of the unit depends on which compressor size you will need,as a guide a 5′ 50/50 will be a 1/5 compressor r600a wereas a R134a may need a 1/4 compressor on the same unit.
