To Next PageTo Next PageWhat to do if the pressure switch did not open on my Carrier 58CTX?
If the pressure switch doesn't open, check if the gas valve is turned off, if there is an obstructed pressure tube, if the manual shut-off valve is on, and if the pressure switch is stuck closed.
What should I check if the secondary voltage fuse is open in my Carrier 58CTX?
If the secondary voltage fuse is open, check for a short circuit in the secondary voltage wiring, including a thermostat component test mode to check the igniter.
What to do if Carrier 58CTX Furnace control doesn't respond to thermostat signals?
If the control doesn't respond to thermostat signals, run the system through a low-heat, high-heat, or cooling cycle to check its operation and disconnect all the thermostat wires from the furnace control. Note that status codes are erased after 72 hours.
What to do if the LED status light is not on in my Carrier Furnace?
If the LED status light is not on, check for correct line voltage polarity, check for continuity in the wire from the circuit breaker to the furnace, replace the transformer, replace the door switch, or replace the furnace control.
