The freezer defrost termination switch was blowing the main breaker in my sub zero 690. I noticed a pinhole in the switch and replaced it. Before I realized that I had a pinhole in the evaporator line matching the pinhole in the defrost termination switch I lost a lot of freon. I patched the leak but now the freezer does not come on. A repairman came out today and claimed that the entire system needs to be replaced under warranty and it will only cost me $1500. He claimed that my system control board was okay but there was only 10 lbs of pressure and it requires 16. The refrigerator side works fine.
Hello, so only the evaporator line only has a leak? compressor and the suction line are ok? how did you patch the hole? and was it leaking for a long time ? thx randy
leaked for about 24 hours; that is the only leak I'm certain
patched it with JB weld putty
what was used to patch the evaporator?if it had a hole just about alll the freon wouldve leaked out pretty quick
sorry ,you beat me to the punch there
it was a pin hole and when I noticed it the next day I could still feel freon leaking out; i think the terminator switch was actually patching it.
parts should be under 12 yr warranty , he is charging you $1500 for labour?
yeah, he wants to replace everythiing and told my that since the pin hole had been patched with putty he couldn't repair it
this is the only factory authorized service center in the SF bay area
how old is the fridge again?
isnt' it weird that the freon would punch a hole in the evaporator line as well as the defrost terminator switch; am I misinterpreting what happened?
that seems a bit excessive ? the compressor should be ok if it only leaked for that short of time ..changing the freezer evaporator and suction line isnt fun and could take 3-5 hours , i would think the labour for something like that would be half the cost ? ive done it and was in and out in 3 plus hours ..charged $600 labour , I would call Sub Zero and see if they are willing to do something as far as the labour goes , they are pretty reasonable , they may give a concession for 50% labour or more ..but i think that quote is definately on the high side
Can't the pinhole be patched? What caused it?
it wouldnt be the freon that pinched the hole ,it wouldve been the electricity that runs through the defrost thermostat
is that common?
shorting against the metal, no very uncommon
so now that I have a working switch why won't the freezer restart?
if you are sure the evaporator is sealed completely .you can get a local guy to just recharge the system. but he will leak test the system
it will be a vacuum of the system and recharge
can the pinhole be sealed with solder or something more permanent/reliable than the putty?
yes, all the copper connections but the evaporator is aluminum , that is why they want to change it
hard to get aluminum to seal ,torch too hot it `will just melt
only the ends are copper
you know I might not have explained it quite right; the line with the pinhole is copper and feeds directly into the evaporator that is next to the icemaker ...
maybe evaporator isn't right ... condenser???
the control bulb will still damage the evaporator , the evaporator is in the freezer section , the condenser is the coil up top where the compressors are ,and a fan in front of it
okay so the pinhole is definitely in copper
yes if it is in copper and you have enough room to weld it in place with proper protection and the hole is not excessive . a small dab of silver solder will fix it , all depends on room and confidence of the person doing the welding
it is generally tight in that area with little room
so any good refrigeration guy can recharge the system and then if there are no leaks it should start to cool again? Does 10lbs of pressure mean that it can't cool and so the compressor doesn't run?
compressor was working fine before the switch shorted out
if it doesnt have enough freon it wouldnt cool ,even if compressor runs
and yes if you get any guy to repair the weld then it wouldnt require any warranty parts
right but compressor isn't trying to run since I replaced the switch; does that indicate something else is wrong?
it would still need the system vaccuumed and recharged and possibly a filter drier changed
what should that cost?
if compressor doesnt run it may have blown the overlaod on the compressor ,it protects the compressor
okay thanks; any recommendations in the san jose, ca area?
where is the compressor overload switch located? is it resettable? replaceable?
sorry not off hand , but i would call subzero customer service there may be another servicer in the area? and see if they are willing to do something for you on the costs
replaceable , it is in the electrical box that attaches to the compressor
you can check it for continuity if you have a meter?
thanks, XXXXX XXXXX one of the things I unplugged to see what was causing the breaker to open. ill check to see if I left a lead off; yea I have a meter; how do i check it?
\one terminal on the terminal and the other terminal on the other side pin hole connector ,it should have continuity
test lead sorry
test lead on terminal other test lead in the hole connector
so it is a break once?
yes, if it goes it wont reset ?if there was a short it probably blew
okay, thanks Randy 43; you've been very helpful
no problem good luck,let me know if i can help you further
