Hello.
So I have an issue with my heater. On a generator my heater turns on but blows cold.  It is an all electric heater so there's no pilot or gas to it.  I have tried two different gens. A 4k and a 10kand still no heat. I know it works because when I put an adapter on and plug it into the the 120v plug in the house i get heat instantly with no waiting for warm up. Any advise? Thanks Fam

I doubt it is a grounding issue.. if it is somebody messed you up royally.

Alas. I'd have to be hands on to diagnose.

I think I'll have to disagree with John.  I suspect it IS a grounding or 'return' problem.  Generators usually do not have earth ground and neutral connected while shore power sources do.  If the furnace heating element is wired across 'hot' and earth ground instead of hot and neutral, I believe this problem would occur.  When connected to shore power, the heating element would be connect to neutral via the earth to neutral connection.  But, when powered by a generator, there would be no complete circuit.


However, I do agree with John that hands on diagnosis would be much more accurate.

What make & model of heater? And what sort of adapter does it need to use household 120v power but not needed in the rv?  It sounds to me as though the adapter is the key - it works with it but not without it.

I see you have also posted this question in the pop-up section, so I merged the two topics here.

I have a 1990 Coleman pop up with a 12v heater I think 12k btu. It's just weird to me since I hooked it up to two different generators.
