When I turn the machine on it says check filter, and won't ignite. I've cleaned the filter including the squirrel cage, and still no luck. Any help will be greatly appreciated. Thank you.
Answer Hello Jim,
If you take the vent off the back and the light stays on then you would need to replace the sensor bar. on the filter housing. If the light goes off then you would need to clean the venting all the way to the outside of the house. You would especially want to check where the duct ends outside of house for lint build up.
