Suburban heater question

[mikenmo]

I've searched the forums and haven't found tis so here goes....

We are now living full time in our Tour TD. This past week it has been cold, for everyone I know, but my sweetheart is especially warm blooded. The Suburban heater in the rear blows air into the floor of the bedroom and bathroom. The problem I'm having is sometimes it will light and sometimes it won't. When it does it warms up great but otherwise it just blows cold air. When it doesn't light, it will cycle off and seem to try again, and sometimes it will light but sometimes it just keeps blowing cold air.
Any suggestions?

When the furnace tries to light and fails, the blower comes on to make sure it dissipates any fumes or carbon monoxide. When it comes on without the furnace lighting, it will blow cold air and then shut off after a timed cycle, this is normal. I believed it is programmed to try this start and run cycle several times before it stops completely for a period of time and then the whole cycle starts again.

Not lighting constantly is a problem, it could be a blockage, board or igniter. Look in you manual for a trouble shooting section.

your moho is kinda new and should have some kind of warranty.

we are plugged in to shore power and use 3 electric ceramic heaters set on 750w most of the time, supplemented with the propane furnace.
