Gas valve.. Keep or Toss?

Hi, new member here. Had an odd episode with my Suburban NT propane furnace that has left we wondering.

Short story.. while cleaning the furnace, I inadvertently wired one of the gas valve solenoids backwards. The strange thing is, the valve remained stuck closed even after I switched the wiring around. So, I opened it up and found the valve slider under the solenoid stuck in the closed position. After freeing the valve slider and reassembling, the valve works perfectly again.

Question - the issue is I know these gas valves are "non-serviceable" but in this case, working on it seems to have fixed the problem. Regardless, should I toss it and buy a new one, or keep this one and move on? - Thanks

    The coils are DC so no polarity issue.


    Thanks for the reply. Yes I'll most likely get rid of it.

    The solenoids have very clear polarity markings on top. I thought perhaps when wiring it backwards, the solenoid operated "in reverse", causing the valve to become stuck closed. Just guessing..

    Well I already replaced the gas jet and the burner, so might as well go all the way and get a new gas valve as well. Should be good to go for many years.
