Endurance 50 & control board troubleshooting

My workaround was to keep the auger motor connected and measure voltage across it, rather than on an open circuit. That sufficiently bled the leakage and displayed around 0 volts, even when the auger was being called for. Dealer then confirmed both boards were bad by plugging them into another stove.

I believe you can use a low-z mode on a meter to accomplish the same thing or, as Matt at Fahrenheit recommended, check for current instead of voltage. But I don't have a clamp meter and was hesitant to use a DMM in-series without knowing how much current would be drawn in a potentially bad circuit.

I have a solenoid style voltmeter that bleeds off 'ghost' voltages right quick (vibrates in your hand ), but I didn't want to stick that in a circuit with sensitive electronics in case it drew too much current and fried a component (if it wasn't already). My understanding is a good meter with low-z doesn't draw near the amperage of such a solenoid style and kicks in protections (increases impedance rapidly) if too much current starts running through the meter. I actually decided to buy a meter with that mode after this.

 

For your research reading/purchase of a low impedance meter. Its a nice spread sheet.

Hey im have same exact problem as urs.
Where did u source the control board?
I need 1

 

Try the Fahrenheit Manufacturer and speak to Matt.
