The on/off switch to the air flow unit. model # ***** 2103-50-1 serial # ***** All I did was take out the 2 filters, clean them and put them back in. Instructions say to turn unit off before removing the filters which I did and when I put them back in and turned the power button to on, the light did not come on. Hope I mde myself clear this time. It's pretty simple.
HVAC Technician: Tim H., HVAC Professional replied 3 years ago
I apologize, I'm not bringing up that model number nor do I know what this is, so I'll opt out for other experts.
