521 heater control

[dbuzz77]

I assume the heater temp control is the knob way down on the heater box. mine won't move. this is a water valve? do you have to take it all apart or is there just a cable there? thanks

you can try taking the white knob off and using some vise grip to get it to move back and forth . other than that what i do is disconnect the heater hoses/controls and remove the heater box. then you can take a wooden dowel and stick it in the bottom hose opening and tap the valve out to clean and reassemble. there is one little very tiny screw that holds the valve in.

 

or the core will come out leaving the heater box in. the face on the box has 3 clips. also remove the hoses and duct boot.

the main thing is not to break the white knob. nobody wants to sell them and then they want around $30 for them.

ok, thanks. it is on right now so the heat comes in in the hot weather.

here's how I solved the handle prob....post 93. If you move ahead a couple of pages to about post 159, there's some pics of taking the valve out

It was fun :)

 

...oh...I made a recommendation to another member and he tried it....worked great. I said I though a garden faucet handle would be cool on there....he got one and it fit great...nice red one :)
