Fan Circuit Breaker (20-Amp)
The original bimetallic breaker is susceptible to internal oxidation which increases electrical resistance at the contact points. This creates a feedback loop of heat within the component, causing the thermal strip to reach its trip-point temperature prematurely even if the fan motor amperage is within normal operating limits. Replacing the breaker restores the original current-carrying capacity and thermal threshold.

Radiator Cooling Fan Motor
If the breaker is functional, the motor may be experiencing high mechanical drag due to bearing contamination or partial winding shorts. This increased mechanical resistance forces the motor to draw higher amperage to maintain RPM, exceeding the 20-30A limit of the protection circuit and causing a legitimate thermal trip of the breaker.

Fan Power Relay
Internal arcing across the relay contacts can create a high-resistance junction. This resistance not only drops voltage to the fan motor (reducing efficiency) but can generate enough heat through the wiring harness to contribute to the thermal tripping of nearby breakers or cause the relay housing to deform, leading to intermittent continuity.
