Only System - 2006 Rheem furnace System operational and home 72° on arrival. System is having intermittent heating issues. All parts in furnace are subject to failure at this age. The flame sensor and igniter are weak, the inducer draft motor is weak and over amping and the bearings are worn. The blower wheel is dirty and the blower motor is over amping weak. The heat exchanger is compromised with rust and metal fatigue. Due to the age, condition, and reliability, I recommend updating the equipment. After testing the heat cycle a few times the system was going out no flame detected. I offered to remove the flame rectifier, clean it and reinstall it. The homeowner opted for this option at the time. After completing the work I cycled the system through heat 3 more times and checked resistance on the flame rectifier. System is currently heating. Still recommend updating the equipment due to reliability. Thank you for choosing T.E. Certified, have a great day!
