    Post Need Guru Help on Refridgerator !!!!!

    I have a refrigerator which hums but will not start compressor. I suspected the PTC relay, took it and put a 100w bulb in series, noticed that its taking almost a minute to switch off the bulb. Is this normal? Because I once had someone say the bulb has to flash only and switch off. please help.

    I never hooked a light bulb to a PTC.

    I always checked it and replaced as needed.

    Interesting, I never heard of it done that way.

    If I was working on this job, I would remove the PTC and install a kick start kit.

    Where do I get a kick start kit? How does it work?

    They're a prewired start capaciter/relay assembly. 2 wires go in (supply) 3 wires come out (compressor common/start/run). Check compressor hp and terminals match. If it still hums compressor is DOA.

    If the compressor hums the internal is seized and the compressor is properly bad. Also what are the RLA on the compressor. that will let you know if the compressor is bad.

    By putting the 100W bulb in series you are dampening the boost the compressor needs to start. It may very well last for an extended period of time.
    Try a new capacitor or one of those kick start kits. The kits are cheap enough so you can try it, but in my experience you will either be buying a new compressor now or soon even if the kick start gets it working.

    By that unit humming you are overheating the coils and if it was good you are putting additional stress on it.

    Not true. Relay could be bad, could be restricted.
    If you really know how it works, you have an execellent chance of fixin' er up!

    I have had good luck with kick starts. I always let the customer know their options and let them make the decision after giving them the facts.

    Yea its a roll of the dice. it may work but you have to at least let them know you are trying to save them a few bucks but the compressor may be living on borrowed time.
