Thanks. I'll get the voltmeter out.
One think to check is the ECO connections (RED Wires)
When using Electric the ECO is still in the control circuit
On propane 12V DC goes to/thru ECO to gas valve solenoids to open gas valve.
On electric---millivolts go to/thru ECO and to gas valve then to ground
Millivots used to confirm ECO circuit and allow ECO to function/shut down heating on Hi Temp Trip (180*F)
Circuit Board doesn't sense the millivolt circuit then NO electric heating
Propane can still function cause 12V DC is used
SO if ECO/Gas Valve terminals are dirty/corroded/loose etc it doesn't take MUCH resistance to stop millivolts (High resistance can stop 12V DC also---but your propane is working)
Just something to check if no 12V DC on YELLOW wire...but have DC on WHITE wire
