One day the freezer was very warm and we lost some of the food stored in it. The previous day I had taken some meat out of it and everything seemed fine. I’m guessing it may have gone into the defrost mode and never completed the cycle.
I’m trying to locate an electrical diagram so I can troubleshoot this thing. I removed the cover from the bottom and searched… no success.
Is there a source for these diagrams or would someone be kind enough to send me a copy??
Thanks
Use a thermometer to monitor temps, food thawing is a problem… Check to see if fan inside is operating (with door switch pushed in manually if so equipped), inspect lower rear of inside back wall for frosting condition… A faulty defrost circuit will cause the evaporator coil to ice up, restrict air flow and in turn temperature rise… The coil will be located behind this rear wall cover, remove to expose the coil if you’re not sure of icing condition… Removing the ice with a hair dryer will get you freezing again but further diagnostics will be needed to correct the problem… Post again if these conditions recur.. cheers, kooler
Thanks Kooler for your reply.
I went ahead and plugged in the freezer, the compressor and fan started running. Placed a thermometer inside and about 3 hours later I checked the temp, it was about 7 degrees.
I didn’t molest anything before plugging it back in other than to look underneath for the electrical print.
What should be next?? Should I let it run for a few days and look for an ice up condition?? After it acted up initially and I unplugged the freezer there was no moisture running out from underneath the freezer.
Thanks
I found pics of your model at the searsparts website so try searching there for more data… I’ve found APPros prices competitive with Sears so I recommend them if and when it’s determined you need new part(s)… Yep, let this unit run for a few days while monitoring temp, keep a log if necessary; try to notice if the compressor cycles off and on by the thermostat, you’ll want temps in the -5 to zero °F zone for storage of seafood or ice cream… +7°F sounds normal after only 3 hours from being unplugged for hours or days… An icing condition will show symptons within days depending on moisture conditions where the freezer is located… Post back when you know more…
After 1 day inside temp of the freezer is -3F. Everything appears normal, I’ll keep an eye on things for a couple of days.
Bad thing is I’m reluctant to put any food in it without finding the cause as to the defrosting mystery.
Okay, I checked the temp this morning, it is still -3F.
Is it possible that I may have left the door open overnight?? If so, would the lines have frozen? That next day I checked to make sure the door was closed (wife may have closed it), but the freezer never recovered.
Thanks.
12 days later… freezer still running at -3F. I installed a freezer alarm, it went off yesterday, temp was up around 25F. Suspect it was in defrost mode. Nothing is in the freezer so there isn’t anything to stabilize the temps. Checked again today, temp is back at -3F.
I’m suspecting that any problems would have shown up by now. I’m leaning toward the possibility that I left the door cracked open and the evaporator froze up?? Since I can’t find any other explanation I will run the freezer with the alarm and keep a close eye on things.
Why don’t they build these things into freezers/refrigerators??
Thanks
Actually there are some models with built-in alarms… But then that’s one more thing that can malfunction; I recall one customer’s response, “Is that what’s making all that racket? Just disconnect the darn thing, if everything’s cold, I don’t need it”…
