Victor July 11, 2012 for Model Number Maytag MCD2257HES We noticed the freezer is working fine but over ther past few weeks the refrigerator side is warm. Figuring it might be the damper or thermistor, we replaced both however the problem still exists. The refrigerator gets to about 43-45 degrees but no colder. The damper sometimes is providing cold air, but sometimes is not. Is there anything else we should check (control panel, automatic defrost controller, etc)? Appreciate the help.
1 Answer Hello Victor. You need to test the thermistors in the unit. It should read around 10,000 ohms at room temperature and around 29,500 ohms at 36°. If it is not reading properly, you will need to replace the thermistor kit 12002355. 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...
Bob May 07, 2012 for Model Number mcd2257hes Fridge is freezing up --poping soda cans Help...Thanks bob
1 Answer Hello Bob. You will need to check and see if the damper WP67003903 is broke or not working properly on the unit. Remove the damper from the control assembly and check to see if the door is broke and is not closing. If the door is not broke, test for power coming to the damper. If there is power there, and the door does not close, you will need to replace the damper. If the damper is opening and closing properly on the unit, then you will need to test the thermistor 12002355 in the control panel. It should read around 10K at room temperature. 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...
Ray April 16, 2012 for Model Number MFF2557HEW Maytag refrigerator model MFF2557HEW has a froze over evaporator. Turn power off to defrost and unit is at room temp. Remove back panel to check heater. Heater has 29 ohms resistance. Thinking the thermistor is bad; proceed to perform Service Test 1 to 6. Service Test 1 - Defrost Thermostat & Defrost Circuit Test does not respond as the instruction sheet explains. After pressing the refrig + button, to start Service Test 1, the Freezer display reads 1; the refrig display reads 4 for about 3 seconds, then goes blank (no character of any kind). There is no power to the heater. Service Test 2 to 6 work like the instruction sheet explains and pass the test. Does the blank refrig display and no power to the heater mean the control module is bad? Thanks, Ray
1 Answer Hello Ray. Based on the information you provided, it sounds like the control board WPW10503278 is bad and will need to be replaced. Hope this helps. Read More...
Pedro April 06, 2012 for Model Number ABR2227FES My freezer is working but is icing up. The fridge section is not receiving any cold air. Can you tell me how to check the defrost system? .
1 Answer Pedro, You will need access to a multimeter. You'll need to remove the freezer drawer, then the freezer back wall to access the heater WP67001794 and the thermostat WP67003426. With the multimeter set for RX1 scale resistance, you will remove the wire connections and check for a "closed" circuit on the heater terminals, and then the same "closed" circuit on the thermostat wires,as long as the thermostat is below 40 degrees F. (a glass of ice water works well). Make sure there are no loose connections or ice in the wiring connectors. You should be able to find the "tech Data" sheet, behing the kickplate grille, in a plastic envelope, and can conduct the tests for all of the systems in the refrigerator. If all checks are OK, you'll need the control board WPW10503278. Here's some meter usage information, should you need it : [http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html] Thanks and Good Luck Read More...
Gene February 19, 2012 for Model Number AMANA - ABB2224DEW I purchased this unit in 2005 and haven't had any problems so far. Currently freezer way is too cold. I lowered the electronic adjuster from 4 to 2 (7 is the coldest setting) but it is still too cold and seems to be getting colder (setting is having no effect). The refrigerator section is about normal but I'm checking the temperature as I type (45Degrees F) but I just turned it back on after cleaning the evaporator coils and fan blade. I need a hammer and chisel to get at my chocolate ice cream. LOL I guessing on my freezer temperature because my A/C thermometer only goes to 0 degrees F. It looks like -20F, my best guess (on setting 2 for the freezer, 7 being coldest). for the past 6 years we have not moved the settings from 4 for the refrigerator section and 4 for the freezer section. the refrigerator section has alway been a tad on the warm side for soft drinks as such. My first thought was the thermostat. I checked under the unit and it was full of dust, which we cleaned and cleaned the fan blades as well. Everything looks good. If it was the defrost circuit, shouldn't the freezer be getting warmer ? Thanks, Gene
1 Answer Hello Gene. If the thermistor 12002355 is bad it will cause the unit not to cool properly. You will need to test the thermistor. Here is a chart to go by. Thermistor Temperature Resistance 77°F..................10,000 ohms 36°F..................29,500 ohms 0°F....................86,300 ohms 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...
James January 22, 2012 for Model Number jenn-air model JFC2089HES Trisensor climate control indicates that both the fridge and freezer are off. Cannot turn either back on from keypad. Unplugged for 15 minutes then restored power. Same condition. Unit is 4 years old, no problems until now. Unit has effectively shut down. No signs of frost inside unit or at back section at compressor. Also, where are mother board/circuit boards located? Is it inside behind interior light assembly? Thanks.
1 Answer Hi James. It sounds like you need the main control board part # WP12782036SP. It is located in back beside the compressor covered in a box.You need to disconnect power and see if the board has smoked or open traces can be seen. Thank You. Read More...
Rick M January 10, 2012 for Model Number MFI2568AEQ The freezer is not cooling down to zero and is not making ice. Freezer alarms out between 15 to 21 degrees. What tests can I do to find the problem? Thanks
1 Answer Hello Rick. Test the thermistor 12002355 and see if it is bad. Thermistor Temperature Resistance 77°F..................10,000 ohms 36°F..................29,500 ohms 0°F....................86,300 ohms You can test this with a multi-meter TJMA-DMT3.

Glenn November 24, 2011 for Model Number 59675529400 I have ice build up on the evaporator coil. The control board, starting relay, capacitor had been replaced & tested the following: ref thermistor reads 12.4k, freezer thermistor reads 13.09k, thermostat read 56.4 @ 70d F, heater reads 10k. Am I right that the thermostat needs replacement? Is there anything else I need to check? Please advise.
1 Answer Hi Glen. The most # 1 cause of the defrost part # WP67003426 not operating will be the defrost thermostat is defective and not closed to allow the heater to receive the 120 vac to the heater part # WP67002493. The thermostat will be closed in temperatures of 14° or close to it. The heater should read 11-18 ohms . This defrost should be controlled by the controls you already replaced part # WPW10503278. Thank you. Read More...
Pam November 13, 2011 for Model Number gb2shtxtb00 I want to check the thermistor to rule it out before I replace the control panel.. the one in the freezer goes up back behind to somewhere. The control panel I assume. I see no wires going in the control panel that match those. Perhaps they are hooked into other wires first? Also can the thermistor be tested without pulling it out?
1 Answer Pam, You can check the freezer thermistor at the electronic control/display panel in the fridge compartment, heres some infor : On the jazz control board connector J2 pin 3 (white/orange) and Pin 2 9white/yellow)Unplug connector from the board and check resistance across the 2 wires , Temperature/resistance at 77°F / 10,000 ohms, at 36°F / 29,500 ohms, at 0°F / 86,300 ohms. The refrigerator compartment Thermistor is mounted to the control panel housing interior, has the same resistance readings and is in the same J2 connector, pin 3 (white/orange) and pin 1 (white). Should you need a thermistor 12002355 will be used to replace either one. Good Luck and Thanks Read More...
James M. November 08, 2011 for Model Number gx5shdxvq01 I came home and my freezer was working however the refrigerator side was not. there seems to be a build of frost in the freezer. The first time it happened I defrosted the freezer and it was working again. I have recently noticed that the frost is building up again. what would cause this? The thermister?
1 Answer Hello James. 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 W10825088 and the defrost thermostat WPW10165425. 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 WPW10503278. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly.
