Title: Vendo 63 fan runs all the time Post by: blackgrizzly on May 30, 2008, 10:18:08 am Hi Guys,
My Vendo 63 cooling fan runs all the time. Unit is plenty cold and it doesnt seem like the compressor is cycling abnormally. Any ideas? Thanks!

the compressors fan should turn off with the compressor when the themostat says the inside temp is cold enough. the inside/evaporator fan that circulates the air inside the bottle area does indeed run all the time.

Thanks! Title: Re: Vendo 63 fan runs all the time Post by: johnieG on May 30, 2008, 12:19:17 pm First note that the wiring harnes controlled by the thermostat is line voltage and can present a shock hazard. :wow:
if the condensor fan is running continuously, (since it's supposed to be wired in Parallel with the compressor) you probably have a defective or shorted thermostat or themostat line/wires. (think of the thermostat as a light switch & the compressor & fan as a pair of lightbulbs controlled by it) To test; First unplug the machine, then remove the wire connectors from the back of the themostat, tape the ends so the dont short out on the metal chassis ( or you! :Oo:) , now plug the machine back in, the fan & compressor should NOT run, if this is so, then you have a defective themostat. BUT if it's still is running, then you may have a short across the wires that go to & from the themostat, or someone's done some creative rewiring of your machines compressor-deck wire harness. |
