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
Completed repairs as approved per prior maintenance service: -Replace blower motor capacitor on furnaces 3A & 3B. -Replace outdoor fan motor capacitor on CU-3. -Replace blower motor capacitor on furnace 6B.
Performed cma full service on 6 split systems. Double air handlers on systems 3, 5, 6. Performed inspection of oven hood exhaust fan and make up air. Split system 1: Compressor megged bad, windings shorted and failing. Ice on refrigerant lines at condenser and air handler. Possible refrigerant issues. R22 system ~25 years old. Due to type, age, and condition of system, recommend replacement of system. Split system 2: Evaporator coil in poor condition and corroded. Compressor megged bad, windings shorted and failing. Temperature difference insufficient in cooling mode. R22 system ~25 years old. Due to type, age, and condition of system, recommend replacement of condenser unit and evaporator coil (furnace relatively new). Split system 3: Condenser outdoor fan motor capacitor tested weak. Provided estimate for replacement of capacitor $203.41. Furnace A & B blower motor capacitors tested weak. Provided estimate for replacement of capacitors $406.82 for both blower capacitors. Spli
