Performed 2 system heating maintenance. Checked amps, capacitors, electrical, safeties, cleanliness, and drains. Systems are performing to manufacture specifications with a couple of concerns. Recommendations U/s 1. Emergency pan is compromised and building calcium on the bottom side of the pan. 2. Inducer motor wiring is damaged and can not be effectively repairs. Recommend replacement of the inducer assembly. 3. System does not have a primary float switch to detect clogging before nit becomes a major problem. D/s 1. Blower motor capacitor is reading 6.6 out of 7.5. This is under the rating on the capacitor and I can not guarantee that it will continue to start. 2. Emergency pan is compromised and building calcium on the bottom side of the pan.
