HVAC Question

I have Reznor garage furnace. The fan kicks on but the igniter clicks and won’t light and then it clicks and tries to light but won’t. Any suggestions?

I’ve had that happen. It’s the thermo couple. You can try and clean it if you are lucky. Just take some emery paper to it where the pilot hits it. Otherwise you will have to change out the thermal coupler. Pretty easy to do.

if it clicks as you say it does not have a pilot or a thermocouple it has an ignitor that is burned out. replace ignitor,

If it’s not lighting at all then it likely not the thermocouple. But you can try to clean it. Find the igniter and see if you can see a spark coming from it.

Usually if you can hear it clicking, the igniter is sparking. Sounds like it’s not getting gas. Maybe bad solenoid, or control board not telling the solenoid to open the valve.

It’s in what they call a soft lock out try shutting off the power for a minute. See if the pilot lites then.If the pilot is off and won’t stay on clean the flame sensor with fine steel wool

Can’t say it any better.

There could be quite a few things wrong. You need to have someone qualified look at it.

Took out igniter and sensor. Cleaned both and works great now. Thanks
