No heat

1008 Views 8 Replies 4 Participants Last post by  jeepgrady
Carrier infinity dual fuel, 3 years old, no heat. Led code 24, according to manual= secondary voltage fuse is open. Check for: short circuit in secondary voltage wiring. Dealer wants $225., just to walk in the door since it's after hours. Have him coming tomorrow instead. Broke out the electric heaters.

Any ideas?

Possible, but unlikely, could be a multitude of things in the low voltage side as simple as a clip or staple holding the t-stat wire against the ductwork or other bonded/grounded material like the gas piping or air conditioning lines, a loose connection to the board that vibrates when the fan is running or a wire pinched in the door frame of the unit etc.
