Chassis Heat - erniecarpet@... - 12-18-2005 09:22 Scott- sounds like your sporlan valves are stopped up- thus not letting coolant circulate. Ernie-83pt40 in texas [Non-text portions of this message have been removed] Chassis Heat - Scott Forman - 12-18-2005 13:55 I cannot get the chassis heat to work in my FCRB. The water is circulating to the back, as it heats the hot water heater as it should, but I cannot get water to flow into any of the heat exchangers. I also cannot make the fans blow. I have followed the instructions in the manual (winter/summer switch to winter, chassis heat thermostat on) but no luck. My auxillary pump works, this doesn't help either. Any pointers? Do the chassis heat fans have an override that keeps them from blowing if there is no heat in the heat exchanger? Where is the valve that the winter/summer switch operates? Thanks Scott Forman 82FCRB Memphis Chassis Heat - Mike Hohnstein - 12-18-2005 14:24 Is the chassis heat thermostat working? Access the heater cores and verify there is no heat to them. The key needs to be on for the chassis heat to work, verify the sporlan valve behind the curbside headlight is functioning. You might be swinging that drivers side front panel, checking them circuit breakers. I have gotten pretty familar with that area of my bus. Too many crimp connectors and not enough relays.

You also must have the engine up to operating temperature to get the engine thermostat to open before you can get any heat at the chassis heaters.

Most likely this is an electrical issue. It can be a bad circuit- breaker, not sure which ones in an '82 RB, could also be the winter/summer switch or its wiring to the dash, you'll need to do some chasing on this. If the chassis heaters are actually getting warm water but not blowing (slide the sofa out and feel the top of the heater after the engine is good and warm) then it is probably either the circuit- breaker or the thermostat, both of which I've seen go bad many times. The summer/winter switch on the dash is common to both the heat exchanger flow and the blowers. - Jeff Miller in Holland, MI --- In WanderlodgeForum@yahoogroups.com, "Scott Forman" <sforman@r...> wrote: > > I cannot get the chassis heat to work in my FCRB.
