Viking model DFFB304L standalone 15.9 cuft freezer. Issue: Freezer trips the Thermistor alarm but also continues to run constantly. Thermistor seems to work correctly. Usually immediately upon plugging in, freezer beeps 5 times and the temp scale flashes left-to-right indicating thermistor alarm. If I clear the alarm, it usually trips almost immediately again. Sometimes it will not trip for a few minutes to few hours, but this is less common. Service Manual indicates that thermistor alarm is triggered by an OPEN circuit at thermistor, which also should cause the compressor and fan to shut off. However it continues to run constantly with alarm tripped. Pulled thermistor while power on to simulate OPEN circuit, and it shuts off compressor/fan immediately. Tested thermistor resistance at different temperatures and compared to book values and it is very close at all temps ranges. Tested both with thermistor removed from freezer and while installed using digital multimeter. Entered the diagnostic mode and display shows what it reads the thermistor temperature. Using the binary code from service manual, confirmed that it is very close to the actual temp (tested with IR gun), so seems that the computer is reading the thermistor, and reading it accurately. Also as I keep door open, the value changes so it seems to be reading constantly and updating. However alarm is still triggered during before, during, after this diagnostic test. Question: Service Manual indicated the only reason for thermistor alarm is if it detects OPEN circuit, but freezer runs constantly, and testing with multimeter and diagnostic mode seem to indicate the thermistor is operating correctly and that the computer is reading the value correctly and consistently. Is there any other failure mode that someone is aware of that would trip the thermistor alarm? Furthermore, any ideas what the issue could be, and how I could diagnose? If it is a problem with one of the PCBs, I have the wiring and PCB diagrams, what should I test to look for an error on the computer?

Whirlpool Thermistor W10838965 rt values chart
Caguitars posted a topic in DIY Appliance Repair Help
Hi, I'm looking for a chart of the values for the above mentioned Whirlpool thermistor. I found the chart for the freezer thermistor on your site and it checked out on my meter. Whirlpool Fridge (wrt318fzdw01) is freezing food in fresh food section and runs constantly. Local tech called Whirlpool and their master tech told them to begin by blocking half the airflow from the freezer to the fresh food section with tape! He didn't put his multimeter on a single thing, just called Whirlpool right away. He put the tape on and left. It continues to freeze food. Before I called the tech I had already run the diagnostics mode and it didn't flash any codes. Thanks, Craig -

DRYER HUMS-Won'T START- WGD9600TW1 -Whirlpool--7 years old
alexakos posted a topic in DIY Appliance Repair Help
Hi. I'm very much an amateur but the dryer is all taken apart now, so there's no going back!When Start is pressed, you hear a hum and drum doesn't turn, and the dryer doesn't go on. So I suspected the motor. At first I swear I saw a PF code briefly. Some people online say the thermistor can cause that error code although I'm not sure why that would be. When I went to diagnostic mode it said F01, which means control board apparently. I did the diagnostics per the tech sheet. The power to the motor on the control board was ok.The thermal fuse was ok.The thermistor had a reading of 16 ohms with a room temp of about 69, which according to the chart I saw means it's bad. It should be 10. It should be 16 at 60 degrees.Per the tech sheet I checked the resistance on the motor and I got a reading of 0 on all three tests: main winding, start winding, and belt switch. Tech sheet says the readings should be somewhere between 3.3-3.6 (main), 2.7-3.0 (start), and from infinity to a few ohms as the pulley arm closes the switch. But I get zero on all 3. Am I doing them wrong? Some sites say the motor should be zero. -

[Webinar] Appliance Temperature Sensing Devices: Bimetals, Thermistors, RTDs, and Thermocouples
Samurai Appliance Repair Man posted an event in Tech Training
untilFour types of temperature sensing devices are commonly used in modern appliances: bimetals, thermistors, RTDs, and thermocouples. We'll discuss the characteristics of each technology, where they're used, and how they fail. This webinar is a joint session for all tech members at Appliantology and for MST Academy students. Professional Appliantologists and MST students will have access to the webinar recording (assuming no technical glitches with the recording). For all the connection details, see the link below: -
