Keep your Broan 655-C bath fan running reliably with genuine OEM replacement parts from Repair Clinic. The Broan 655-C is a combination bathroom exhaust fan, resistance heater, and light unit which is a three-function appliance whose fan motor, heater element, and light socket can each fail independently without affecting the remaining functions. Confirming which function has failed before any disassembly is the most important diagnostic step for this model and it tells you exactly which component to order before opening the housing. Repair Clinic stocks genuine Broan OEM parts for the 655-C including the Broan bath fan motor parts, Broan heater element parts, and grille assembly.

Broan 655-C Function-Specific Diagnosis Before Disassembly
When servicing the Broan 655-C, the first step is confirming which of the three functions has failed like the exhaust fan, the heater, or the light, before removing the grille or opening the housing. A failed motor only affects exhaust ventilation as a failed heater element only affects supplemental heating and a failed light socket only affects illumination. This function-level independence makes 655-C diagnosis far more straightforward than it initially appears, despite the three-function design.
Most Replaced Parts on the Broan 655-C
Motor for the Broan 655-C
The fan motor drives the impeller that generates exhaust ventilation airflow as the motor bearing wears, it produces the grinding or squealing noise that is the primary complaint for failed ventilation function on this model. The 655-C motor is specific to this combination unit housing and must not be substituted with a motor from a standard Broan exhaust-only fan series including the mounting geometry and wiring configuration differ.
Heater Element for the Broan 655-C
A shorted heater element trips the circuit breaker which is an open-circuit element produces no heat but does not trip the breaker. These two failure modes produce identical symptoms from the user’s perspective but require different diagnostic tests, testing resistance across the element terminals with a multimeter distinguishes between them before any replacement is ordered.
Blower Wheel for the 655-C
The blower wheel mounts to the motor shaft and generates the airflow for exhaust ventilation. A wheel that has accumulated heavy dust or lint runs out of balance, producing vibration and additional radial load on the motor bearing that accelerates bearing wear. Cleaning the blower wheel thoroughly before replacing the motor often resolves vibration complaints without any parts expense.
Grille Assembly for the Broan 655-C
The grille covers the fan and heater opening and attaches with spring clips that release by pulling straight down on the grille face. A yellowed, cracked, or damaged grille can be replaced without disassembling any functional component of the 655-C and it is the lowest-cost visual refresh available for this model.

Broan 655-C Bath Fan Parts FAQ
What is the Broan 655-C and what makes it different from a standard bath fan?
The Broan 655-C is a combination bathroom exhaust fan, resistance heater, and light unit in a single ceiling-mounted housing, unlike a standard exhaust fan, it has three independently controllable functions, each of which can fail without affecting the other two.
What motor fits the Broan 655-C?
The Broan 655-C uses a dedicated fan motor specific to this combination unit series, listed on the Repair Clinic 655-C product page under the Motor category. The 655-C motor is not interchangeable with motors from standard Broan exhaust-only fan series.
Why does the heater on my Broan 655-C trip the circuit breaker?
A 655-C heater tripping the circuit breaker has most commonly developed a shorted heating element. A shorted element creates a low-impedance path that draws excessive current and trips the breaker. Test the element for a short circuit with a multimeter before resetting the breaker.
How do I replace the heater element in the Broan 655-C?
Turn off the circuit breaker serving the unit. Remove the grille by releasing the spring clips. Disconnect the element leads and unscrew the mounting bracket. Install the replacement element, reconnect leads, and restore power before testing all three functions.
