Jim May 10, 2013 for Model Number hts17BBMBBCC My freezer has frosted up and the refrigerator section is not cooling. I removed all of the ice and looked at the defrost heater WR51X10038. I did not remove the heater but I noticed that there appeared to be some moisture inside the tube. This heater was replaced about a year ago. Is it common to have moisture in the defrost tube? How can I test to see if the heater is coming on when required?
1 Answer Jim, It is possible for the heater to have moisture in it. One way to tell if your heater is good is if the defrost thermostat is cold you can advance the defrost timer and see if the heater come on. If it does not then test the defrost thermostat for continuity and the defrost heater for continuity. If it does come on then you will want to replace the defrost control WR9X502. Read More...
Joe April 16, 2013 for Model Number GTS22KCPARBB If you replace to defrost thermostat and defrost timer, and then you put in a new heating element is and you still do not get the heating element to come on is there any other reason for it not to come on? Like a mother board problem? Thanks Joe
1 Answer Joe, You will want to make sure that the other defrost bimetal WR50X10068 and WR50X10071 is not bad and that the defrost thermistor if the unit has one is not bad. On the evaporator where the unit bimetal is on the right side there is a second limiter which is on the right side as well and is lower than the one at the top. Read More...
Rich January 06, 2013 for Model Number PTS25LBMARWW I have had to defrost my evaporator coils twice as they were completely iced over. I have test equipment so I would like to test the defrost circuits to determine whether it is the board, sensor or heater circuit. My questions: What is the normal resistance range of the defrost heater? Does the defrost heater typically go open when it fails? Do you have specs for the resistance range of the defrost thermostat? (ohms @ temperature)
1 Answer Hell Rich. Both the heater and the thermostat should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Joe September 15, 2012 for Model Number PTS25LBMARCC - GE Profile Arctica - vertical Hello...I want test for continuity of the defrost heater (part#AP2639820). This element is glass enclosed. So my ohm meter probes must find the ends of the element,where the piece seems to attach itself to brackets. My question is, ..can I test for continuity while the defrost heater is in place?...or, ...must I remove the heater for a conclusive test? So far, I show OPEN continuity, so I assume the part is bad. However, testing is difficult (difficult to see under the coils), and I am not sure whether my test method is appropriate;i.e., whether I'm getting the correct reading. thanks joe
1 Answer Hello Joe. You can test the heater in place and it seems the heater WR51X10038 is bad and will need to be replaced in the unit. Read More...
Steve1147 June 21, 2012 for Model Number htr18abmdrww I can't seem to find a defrost timer on your website for this unit. Thanks, Steve
1 Answer Hello Steve1147. Based on the model number you provided, WR9X502 is the correct timer. Read More...
1 Answer Hello Alice. Remove the back wall out of the freezer and you can access the heater WR51X10038 under the evaporator coils. It is mounted to the bottom of the coils. You may need to melt the ice, if the unit is frosted over, to access and replace the part. Read More...
Jason March 20, 2012 for Model Number HTS18GBMDRWW It seems I have the same problems as both of these people. When should the fan run? Please help!
1 Answer Hello Jason. If the compressor is running on the unit, then the fan motor WR60X10172 should be running. If it is not, test for power coming to the motor. If there is power there, and not running, you will need to replace the fan motor. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Karen B. March 07, 2012 for Model Number gth22shsarss / ge The freezer works fine. The fridge gets warm. If we unplug the unit then plug in after 24 hours the fridge will get cold again, but only cold for a few days. We have repeated this three times. What is our next step? What part should we replace?
1 Answer Hello Karen. 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 WR51X10038 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. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
