Input Needed on CB 6048 Overheating

I need some input and advice. On Friday I came home from work to my OWB spitting out steam from the top vent. The water was boiling and appeared to have been doing so for awhile. Based upon the sight glass, half the water evaporated out. I got some water in it and got it cooled down, but curious on anything I should be looking at in terms of damage?

My best guess is the solenoid valve on the damper failed and didn't shut. I tested it with a multi meter and based upon the specs in the owners manual, and it appears to be bad. I have ordered a replacement, should be here today.

Anything else I need to be looking at? My door seal appears to be good and I don't see any leaks or obstructions on/around the damper. I had it running this weekend when I was around and could keep an eye on it with no problems, the damper shut every time.

I am hoping the new solenoid valve fixes the problem, more concerned about the damage the overheating may have caused.

 

I put the new solenoid on last night, not sure why I called it a "valve" yesterday in my post, clearly its not a valve, brain fart I guess.

Anyway, everything seems to be working....

 

As long as it's still holding water you probably didn't do any long term damage. Damper probably got stuck open. Make sure you keep your new one lubricated, as well as the linkages to the damper plate.

 

^^^^^^^^^^^^^^^^^^^^^^^
What he said! I use PB on mine because it's non flammable.

 

I used to have that happen on occasion with my old CL5648. Solenoid fried >>> damper sticks >>> everything boils. I went through several solenoids. Not really any damage to speak of though.

Edit: For outdoor lubrication I use Fluid Film in an aerosol can. It is, bar none, the best stuff I have used to keep things moving and beat rust too. I am not sure about using it in a high-heat application, however. Specs say it is combustible at 405°F.

 

I assume it is not at the proper fill level-so you can check for leaks (wet spots) inside the firebox. Or clumping ashes. With the water boiling and spitting out, you probably had enough water to cover the firebox and saved warpage. Hope so. Unexplained clumping ashes or dark stained ashes be on the lookout for also.

 

Thanks for the replies everyone. It appears I avoided disaster. I have had no wet spots or clumping ashes in the firebox and it appears to be holding water.

Thanks for the lubrication advice.

 

I would have thought they would have designed that so if a solenoid or motor failed, it would fail closed.

 

They tried to, but the rod gets stuck...hence the need for lubrication.

 

Fluid Film is top notch stuff!!!!!!! It all I use on my solenoid. Last a long time after application.
