Replacing compressor in freezer.

[ecogeorge]

I have a 4 yr old Proline chest freezer bought off fleabay for 99p as faulty.
Item is faulty - earth fault on compressor - ie bu**ered.
Keen to improve my refrigeration skills -don't panic have safe handling of gasses ticket etc as well as vac pump /gauges etc and would like to repair it. Time is not important (other than never enough) rather than the satisfaction of repairing it.
Looking for a cheap compressor and came across these on fleabay -

Any one got any good ideas for 240-115v supply ?  surely a transformer would be inefficient ? -what if I  switched the transformer on with the compressor? 
The driving force here is cheap / recycled / unwanted parts.
Where is frotter these days when you need him

No need to switch the transformer. 230 volt cable that fed the old compressor will supply the 230 volt side of the transformer. 115 volt side then feeds the new compressor.

The transformer can be double wound or single wound. It could be any double wound transformer with two 110 volt primary windings and don’t use the secondary connections.

Iron / copper losses in the transformer only about 4% Again only a loss while the compressor is running.

Not sure about that. My mate can turn his startomatic genny on with his 110 transformer with nothing plugged into it.

So thats about 60w idling.

What refrigerant is it running?..... R600a

Sorry Justme I think you've missed Alans point, - connect the compressor to the transformer and then wire the transformer to the compressor supply - transformer only energised when compressor is running.

Moostie - gas is 134a.

Anyone care to suggest a transformer rating for starting a 100-150w compressor baring in mind the start up currents of freezers.

[Mostie]

starting current should be 5 -7 times the running current, why not just try it on a yellow trannie

[ecogeorge]

hmm , going be hard to hide a yellow trannie under a freezer 

[Mostie]

lol ..... tell the wife its a compromise 

I assumed it was a garage freezer

I've probably got an ancient fridge compressor in my garage somewhere, salvaged from an 80s fridge or freezer - is that any good to you? (Monmouth)
