The Rheem-Ruud PD425117 Relay is a heavy-duty

it is performing its mechanical duty to prevent HVAC fire hazards

When failures in the heating cycle occur

the start relay is likely defective

or a failure in the inducer motor/venting system

Danfoss 117U5017 Start Capacitor The Rheem-Ruud PD425117 Relay isThe Danfoss 117U5017 Start Capacitor is a critical electrical component designed specifically for SC model compressors, providing the necessary torque for reliable compressor startup in high back pressure and commercial refrigeration applications. Rated at 80 microfarad and 220V, this round start capacitor ensures the motor can overcome initial inertia and high head pressures without overheating the windings.
