I changed the ignitor and the thermostat on my weather maker 8000, the fan runs good but there is no flame coming out at all, neither the ignitor will turn red. What else should I check?

Is there power going to the igniter,, check at the circuit board

When you say that the fan is running I assume that you mean the exhaust assist fan. If it is running and the ignitor not getting red you ned to check for power to the ignitor, You can do this by unpluging the connector that is about eigh to ten inches from the ignitor and use a volt meter in the two terminals that you npluged the ignitor from, now turn up the thermostat and see if you have power there, if you do that means the ignitor is bad. You said you changed the ignitor but these things are very fraigle and could have gooten broke. Also do not touch the gray part of the ignitor with your fingers, the oil will make the material burn into.

The fan kicks off after a few minutes
