Montgomery Ward Chest Freezer Cold But Never Shuts Off
I've got an old 1987 Montgomery Ward 15.8 cu. ft. Chest Freezer Model #: 85058/85157 that is running all of the time. It just started doing this at the beginning of the week. The temp inside of the freezer is at -2 below.
Turning the themostat control to the off setting does cause the freezer does shut off. When putting it back to the normal setting, it waits about a minute comes back on but never cycles back off again. I've located a replacement cold themostat for it if that is the problem. Thanks for the help!

The older chest freezers can be very reliable. The problem is finding parts and repair information. I see you found a thermostat. While you wait for the expert to review and provide instructions you can check a similar question answered previously. It is not your model but the advice is pretty general for most freezers. I attached it in the first link below and the second link is to Sears Parts Direct for parts if needed.
Barbara H -- Thank you for the links. After reviewig that info I'm leaning more towards the thermostat as being the problem. The freezer has good circulation around the cabinet and it's about 2/3 full of frozen food. The temp is currently at -5 below indicating the freon level is ok and the compressor is working. With the freezer at -5 below, it's cold enough that when I turn the thermostat control down to the lowest setting (warmer) it should cycle off but doesn't indicating a defective thermostat. I would however appreciate one of the experts in the field to confirm this as well. As of now I'm unplugging the freezer at night to give it a rest and then plugging it back in the next morning until I get it fixed.
I can understand your concern about the freezer running all the time. You have received some good general information from Barbara. Based on the information listed, this is a thermostat problem. Before replacing the thermostat, I recommend adjusting it to a warmer setting. If it cycles off now, it should be ok but if it still runs, the thermostat will need to be replaced.

Hello Scott D -- The freezer never shuts off even on the lowest setting. I have background in electronics and after looking at the schematic diagram I was fairly certain that the thermostat was the likely problem. Thanks for the confirmation and I have ordered a replacement thermostat. There was a rubber like sealant on the bottom of the tube that the temperature probe form the themostat slides into. I will have to remove that to get the old probe out of the tube. Can you tell me what kind of sealant this is or what to use as replacement after I install the new themostat? Thank you!
Scott -- I went to remove the thermostat this afternoon but the probe seems to be stuck inside that tube. Didn't want to pull on too hard thinking that it might break off. I gave it pretty good tug but it seems to be really stuck. We have another old chest freezer sitting around that doesn't work so thought I would try removing the thermostat on that one. I didn't have any problem at all, the temp probe slid right out the tube. Is that temp probe solid or is it hollow and filled with some type of gas or liquid? Any suggestions on how to get it out? My other concern is how difficult is going to be to get the new probe back in there. Thanks!
It's very common for the sensor tube to get stuck and can be very hard to pull out. The probe will be hollow and could have Mercury or Ether inside of it. You will probably need to use some pliers, to get it out. Be careful, so the probe does not break up close to the tube it's in or it will be very difficult to get it out. Also make sure you mark the original probe to see how much of it fits inside the tube because the new probe will need to fit back in, the same amount. Keep the new probe as straight as possible when inserting it back in and it will usually go back ok. If it does get tight you can use some silicon grease to help it slide easier. I hope this will help you.
Yesterday while I had the thermostat control lose from the retaining bracket, I noticed when adjusting the control knob it seemed kind of tight. After working that knob back and forth a few times it loosen up a bit. Decided to give it a little shot of WD-40...figured it couldn't hurt since it wasn't working. That help loosened the control up even more so I reinstalled. Plugged it back and now it's working again. It has shut on / off quite a few times now, apparently the contacts were stuck. Think I'm going to leave well enough alone for now and if quits again, I've got the part sitting here to replace it. On another forum I read that sometimes that sensor probe can get stuck because it's frozen in place due to condensation in the tube. They recommend unplugging the freezer for several hours and overnight then try to remove it. Thanks for all the help!!
