No Heat - 2005 Rheem gas furnace System not heating mainly to age. System has multiple issues that all relate back to the systems age, 20+ years old. The main control board is bad, the system doesn’t always bring on the heat. When it does bring on the heat it runs for a little while then shuts off on high limit. The heat exchanger is compromised, the inducer motor is weak and over amping, the blower wheel is heavily impacted with debris. The blower wheel being impacted with debris is also reducing air flow across the heat exchanger. Pair this with a bad heat exchanger, worn inducer motor, and weak blower motor and the system over heats pretty quickly and shuts down. After going over the condition, age, and repairs, the homeowner requested we send out an install supervisor to go over updating the full system. I scheduled this with dispatch for 4pm today. Thank you for choosing T.E. Certified, have a great day!
