Technicians should verify the seal integrity during any blower assembly maintenance to prevent CO leakage or erratic burner performance

Look for physical bulging at the top of the canister or use a multimeter to check if the capacitance has dropped more than 10% below the 55 microfarad rating

Can I bypass the 160F limit switch for testing

this unit is typically rated for up to 40A resistive loads

preventing the motor overheating and high energy consumption associated with degraded dielectric film

MARS 12790 Run Capacitor Technicians should verify the sealThe MARS 12790 dual run capacitor is a heavy duty 50 5 MFD 440V round capacitor designed for high performance HVACR motor and compressor applications. This dual rated component provides the necessary capacitive phase shift for both the compressor and the condenser fan motor, ensuring efficient start up and lower running amperage. Built to EIA 456 A standards, it features a metallized polypropylene film dielectric housed in a rugged aluminum casing.
