WARNING do not take a gas appliance to this service center,, they took it apart to clean out the dirt dobbers ,, while reassembling they did not tighten the compression nut going to the regulator therefore there was not enough gas entering the chamber to ignite but gas was circulating into the vents and throughout the camper,, SO, because it would not light they decided to replace the circuit board ($165.00) still it would not light ,,SO replace limit switch ($29.00),, both at my expense,, then $150.00 labor,,,,,,, IF they had of reassembled it correctly it would have needed a board or switch and they would have charged me the $50.00 as agreed upon in the beginning !!
