I have a weird problem, I think I know whats wrong but figured I'd see if anyone else has any ideas.

My heater (and I've tried a couple different ones) will only stay on for a few minutes max and shuts down. Its not even remotely close to hitting the right pressure, like maybe 600 psi and its off. It literally only stays on for 2-3 minutes, maybe less. I'm figuring its gotta be the pressure switch, lost my damn volt meter so I haven't been able to meter it to see.

Its a pretty simple circuit, and I have tried a couple different heaters, so I can't imagine what else it could be? Are these supposed to be adjustable or do I just buy a new one?

 

The pressure switches are there for your heater to heat the bottle to a desired psi then shut off. Theres defiantly a problem. Question: Have you always had this problem even since the beginning of the heater install? Or did it start acting up after a while?

 

take the pressure switch out of the circuit and see if it goes away?

adjust the pressure switch?

just thinking out loud

 

as already said, if you have a pressure switch it may be bad, unless its adjustable, in which case adjust it higher.

Unless your heater is thermostaticly controlled (Zex, and some NOS), then get used to under heated bottles.

 

Like Vinny and everyone else said...First let us know what kind of pressure switch it is and if you've tried adjusting it.
