Found this in a manual about 240 k ohms.That interesting.Sounds like that resister is inside the defrost thermostat .Why i don't know but i know i have used a WR50X50 IN THE PAST and change the board with no call backs.But this is not your problem.Its interesting maybe someone else would know about that 240 k ohm resister.I know when i cut it out off the heater it would read zero ohms on a low ohm meter scale when it was closed.Weird.

The Resistors on the ADC will get warm when the Relay is ON (Defrost mode).
The Relay should be ON for a maximum of about 30 minutes,
whether or not the Defrost Heater is energized (Defrost T-stat temperature)
The 240k inside the Defrost T-stat is a "marker" used to easily measure the entire Defrost Circuit,
wheather or not the Defrost T-stat is "open" or "closed".
