heater Fan Run Time

[jake2250]

I searched but cannot find an answer,,

It seems that my heater fan comes on before the heater lights off. The fan runs for almost 40 seconds then you can hear the heater light off, when it reaches set temp you can hear the flame shut off but the fan continues to run for up to a minute!!
So it starts blowing cold air then ends by cooling everything off again.

My question: Can I adjust fan run time?

On our Pop Up trailer the little heater fan would come on for like ten seconds then the heater would light, then at temp set the flame would go out and fan would only run for about fifteen seconds..

It aggravates me too but that's how they work.

ksg5000 nailed it....your system is working exactly like it needs to do, don't change a thing

Sounds like the heater is working fine. What's the issue? For safety reasons the blower is suppose to start first which lifts a "sail" which then tells the heater it OK to commence the ignition starting system. The fan is suppose to run for a while after the heater shuts down to cool down the system and maximize the heat value.
