Boilover on a regular basis
« on: October 31, 2013, 04:55:08 PM »

We have a couple year old 4400. No problems until this year….The set point is 170 and the stove regularly goes way past to boil over.

Pump works fine and fan works fine…

Where should I start looking?

does this model have the fan and damper on the door? if so make sure the fan damper is closing ,just cause the fan is working doesnt mean the damper is closing.

Solenoid could be a bit rusty or door gaskets...  Spray solenoid with some oil and manually work it up no down

Noob, with same problem, purchased a house with a Woodmaster 4400 installed, boiling over.  What does a good door gasket look like and where is the selinoid that might need spraying?  Thanks in advance.

Check your loading door gasket where you load your wood into, check your ash cleanout door if your model has one. Your solenoid is under that cover on the front door. What it does is lift a small flapper door that covers the intake for the fan so that it doesn't pull air through the opening for the fan when the aquastat is not calling for heat. Make sure that this door is also sealing over the fan opening.

Honda racer, thanks for the input, you are 100% on the money.  I looked at this last night, the door seal is not tight was creosoted up and the little rubber flapper had dry rotted a 1/4" crack in the bend.   I replaced the door seal with a 5/8" seal which was too small but got me going and ordered a one inch door seal online last night along with a new flapper.  The stove is currently working properly with no runaway temps.  I also found a manual online which always helps. 

The stove is a Woodmaster 4400 Heavy Duty model.  The more I use this the more I like it.

To help pull the door tight for now, I slid some lock washers over the door bar for a spacer that rubs or contacts with the inner wall.  In an emergency with a leaking seal, this might be something a person could do until there parts arrived.

Glad you got it figured out. Most don't think to check the seals each year but it is common for them to only last a season or two before needing replacement. I have a buddy with a Shaver(yeah I know :bash:) who had runaway issues constantly. We put the fan damper mod on it along with replacing the awful silicone door seals. No more boiling!
