As stated, I have a 2003 FR Sandpiper 30GT and the Control Box in overhead AC keeps clicking only when I run the Furnace. The furnace WILL Ignite and run but that Control box will be constantly clicking all night long. I changed the control box, changed the thermostat (Non Digital), even tried a new digital TStat that came with the new control board but that just made the blower start and stop constantly. Furnace is a Suburban SF30. and doesn't matter if it is on shore or battery power. Can anyone point me in a direction to test or look? Bad ground? Converter? The control module in the furnace itself? This even has my local RV dealer Stumped
