Are you closing to many registers?

Are too many registers closed?

Do not close off more than 20 % of the registers because this can

cause high resistance and unnecessary heat build up in the furnace.

It's OK to close some registers to save on energy costs if rooms are 

 unused...but do not exceed 20%. So if you have 10 rooms, you 

should only be closing a maximum of 2 registers.

The furnace will get to hot and shut down on a limit over load. You 

will have to turn off the power 

to set the furnace.
