Thanks everyone for the replies. I was able to get the cover off the K1 relay and close the contacts with a toothpick which then powered the AC heating element, but I have to close the gas valve since the board still tries to light the gas. So far, I haven't been able to remove the K2 relay cover. I'm camping and don't want to break the board until I get home. Am I correct in assuming the K2 powers the ignition module? As of right now, it works correctly. The voltage across the K4 resistor drops to 1.4 volts. Is 1.4 volts too low for the power supply board to sense AC power? It appears the K4 resistor has been warm and may have damaged the IC chip next to the resistor.
Thanks again for everyone's help!

Unless you just want to learn more or repair it yourself now that you know there are problems with the board and if the MH is a long term keeper you may want to consider ordering another board tomorrow so when you get home it will be there soon.
Any sign of over heating on a board typically means there is more unseen damage kind of like roof leak damage.

Looks like I will be replacing the power supply board. Something I noticed this morning while running on gas in the campground. I have a very slow drip of water running down the tubes, but unsure where is coming from. I checked the drain tube from inside the refrigerator and it's dry. The best I can tell, the drip starts from the burner side of the refrigerator. Any ideas or should I be concerned?
Thanks

The pipe coming out of the back after the exit from the bottom of the foam block will sweat and drip like a metal AC line on your car will. This is normal I have been told but I am considering wrapping mine with the insulating tape made for AC use for cold/cool metal lines.

Thanks. That sounds like the problem, it has been really humid here as well.
