fridge warm/ freezer not freezing and frost on wall

Refrigerator & Freezer Repair

I have a Hotpoint Model HSS25GFPJWW it was making the clicking sound and fan trying to move, figured out the main board needed to be replaced. Replaced it and the fridge worked fine for a few days and I noticed that the fridge started to get warm and freezer has frost on back wall. I’m new at repairing things and was told to check the continuity for defrost thermastat and heater thermastat? How do I go about this procedure. I do have a digital multimeter, not sure how to use it. If anyone can help please help!

Here are your parts

Unplug the unit and remove the evaporator cover in the freezer so you can see the coils.
Do not let them de-ice.
If they are heavily iced/frosted over you have a defrost problem.

Unplug the unit.
Remove the wires at the heating element (Item 230 in Section 3) and measure it for continuity, usually around 20 ohms or so.

If the heater is OK
Remove one wire to the defrost thermostat (Item 240 in Section 3) and measure it, should be 0 ohms when frozen. Note that it opens just above freezing so must be frozen to check it. Also inspect it, if it is bulged at all replace it even if it measures OK.

A couple things to watch when measuring ohms and continuity

  1. Always remove power from the machine otherwise you could blow your meter.
  2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
  3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale’s dynamic range.
  4. When you start always short the meter leads together. This will tell you that the meter is working and if there is any 0 offset.

There is a good STICKY at the start of this forum about it’s use.

thank you so much for your quick reply and my apology for a slow reply. as you can tell im kinda slow, have lots of projects!? :slight_smile: ok i just tested the heater element (Item 230 in Section 3) and i dont get a BEEP! so i am guessing that needs replacing?
