Refrigerator is freezing up.
Answer Hello Lyle. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My freezer is freezing up around the drain hole. I am wondering if the defrost is not working. The water is building up on the freezer floor and running out on my floor. Any suggestions?
It isn't that uncommon for the defrost drain to freeze up. Three things generally cause it to happen. Items finding their way int the drain and stopping it up, (i.e. price tags, food product labels, etc.), freezer temperature too low, and the drain trap developing an algae.
The first thing you must do is remove the back freezer wall to access the drain. Use a hair dryer to clear the ice build-up. Use a piece of weedeater line to "chase" the line. Never use wire or anything that could puncture the rubber and plastic drain line material. Pour in about 2 tablespoons of white vinegar to prevent algae formation and set the freezer temperature to a warmer temperature to allow the defrost moisture to drain instead of freezing on its' way to the drain It's a good idea to set the freezer temperature to an average setting of 0°F to 10°F using a freezer thermometer. It takes about three days to zero in on the average operating temperature. Only check the temperature first thing in the morning, after the unit has been closed all night. Only make one setting adjustment per 24 hour period. Remember that refrigeration is a slow process and if you make more than one setting adjustment in 24 hours, you are lost and until you allow time to pass, you don't know what temperature the unit will average. (Average temperature is based on the fact that there will be a 10° "sway" of operation. The unit will warm up to a certain temperature before the compressor kicks on, then it will run until it gets down to a temperature that satisfies the thermostat. This is the 10° sway of normal operation).
