Next we need to check the resistance between both wires coming from the heating element. Depending on the wiring configuration, this can be checked in two places.
-
For modules manufactured prior to 8/1/2014, we will touch the multimeter probes to both connections on the terminal strip, as shown in the first photo.
-
For modules manufactured after 8/1/2014, we will touch the probes to both thermal reset leads, as shown in the second photo.

While measuring the resistance, the value on the display may float for several seconds. Once the value stabilizes, it should read between 20-26 ohms on a 220V machine.
-
If the value is out of this range, please contact Modbar customer support, as the heating element may be damaged.
