Heating tune up performed today on a down flow propane furnace with a straight cool condenser. All electrical connections are tight with no corrosion. X13 blower motor is acceptable. Blower wheel and evaporator coil are clean. Inducer motor is pulling proper amperage. All safeties are working properly. Refrigerant levels are in range. Need to order a plastic clip for the furnace door. Customer states that we broke it and it has not been replaced yet.
