Tech found fuse blown causing a voltage drop due to both 5a and 5b feeding off the same transformer. Tech found both systems run properly individually , but when r is connected, the fuse blows. Tech wired all other wires to both boards and found systems operating properly.
-Performed repairs as recommended at prior maintenance inspection per approval: -System 2: Outdoor fan motor not operating via contactor. Observed extreme delay in operation and fan motor running at excessive amperage. Rated at 0.98 FLA on unit, 1.6 on motor; running at 3.26. 208/230 1/6 HP 1625 rpm. Motor was overheated and on thermal overload upon arrival. Replaced motor & capacitor per prior approval. Verified proper operation of motor. -System 5: Observed ignition on furnace 5-B then immediately cuts off. Cleaned flame sensor and retested. Heat still would not stay lit. Swapped sensors with twin furnace, problem remains on furnace B. Control board eventually gives error light of solid continuous: replace IFC (Indoor Fan Control). Replaced control board per approval. Demand tech to follow up on part installation & identify any further system needs.
-Performed CMA Inspection on 6 split systems. Dual air handlers & evaporator coils on systems 3, 5, 6. Verified operation of oven hood exhaust and make up air. -Split System 1: System was recommended for replacement August 2023. R22 system ~25 yr old. System found frozen at condenser and line set at that time. Compressor failed megohmeter test and found to have shorted windings. --Split System 2: System was recommended for replacement August 2023. R22 system ~25 yr old. Compressor failed megohmeter test and found to have shorted windings. Found evaporator coil in poor condition and corroded. Temperature difference was found to be insufficient. System has relatively new furnace and was recommended to replace condensing unit and evaporator coil. Outdoor fan motor not operating via contactor. Observed extreme delay in operation and fan motor running at excessive amperage. Rated at 0.98 FLA on unit, 1.6 on motor; running at 3.26. 208/230 1/6 HP 1625 rpm. Provided estimate for motor repla
