After testing the t-stat and the power converter panel with a volt meter, I found that there was no DC voltage from three fuse blocks. After a phone call to a local RV service technician I learned that the half of my power converter that provides DC to the heater, the water pump and charges the house batteries is toasted. Most likely because the house batteries needed to be replaced for a long time and the coach had been on AC power resulting in the charger being overworked.

Long story short...as a temporary fix I disconnected the house batteries and ran a jumper from the good side of the 12 volt supply and now I have heat. Soon the converter and house batteries will need to be replaced for about $500.
