Troubleshooting :

If the indicator light does not come on when the furnace is running please check:

1) Is the Unit plugged in?

2) Is outlet active? Test with lamp.

3) Is unit switched on? Turn to #3.

4) Is fuse OK? Switch unit off to check.

5) Is air sensor tube damaged, kinked or not connected?

6) Is furnace filter plugged?
This will effect the static vacuum level required for the air sensor. To test, partially remove filter to allow for more air movement.

7) Is ozone being produced?
To test, remove red tube from cold air duct and hold to the palm of your hand for 30 seconds. You should be able to smell ozone on your hand.

DO NOT breathe direct output of ozone
