Electric gas solenoid runs hot
I have an electronic solenoid switch controlling gas flow (from my gas cylinder in its cockpit gas locker) to my galley stove. It’s a 12v system. I noticed my solenoid is very hot to touch after being on for 20 minutes. It was a cloudy cool day, low 70’s. Is this normal?
Hi Warren, My boat has a fairly common 12v Fireboy Xintex S-2A propane controller, and today I used a laser temp measuring pistol to check out its solenoid. What I saw surprised me a bit but is probably just what happens when electrons activate a good magnetic flow switch over 20 minutes or more. The temp difference between the Maine air and surrounding propane cabinet was about 30 degrees -- the solenoid about 90, the rest about 60.
I don't know for sure but I suspect that's how it's been running for maybe 20 years, 10 under my ownership. And the boat has not blown up. But if your solenoid has a greater temp delta than that, or if it's skin-burning hot, I'd be concerned.
