Kwaich HN61PC002 HVAC Air Handler Relay
Coil: 22VDC. Contact rating: 30A, DPST-NO (2 Form A). This 6-terminal quick-connect relay is designed for HVAC control circuits and commonly replaces HN61PC002. Best for HVAC systems using a rectifier/control board and 22V control signals. It fits replacement paths that reference HN61PC003 in some diagrams. Use this when your unit’s wiring diagram calls for a 22VDC, 2 Form A relay with 0.250″ terminals.
Who it’s best for: technicians replacing a failed air handler blower motor relay in Carrier-like or similar systems with a 22VDC control signal. Why selected: matches function, coil, and form factor; supports high switching loads. Caution: verify the exact part number and control board markings on your unit to avoid mis-match with 22V vs 24V coils.
FurnyQuaint HN61PC002 Carrier Relay Replacement
Coil: 22VDC. This is an exact replacement for the OEM HN61PC002 part, designed for DPST-NO operation with a 30A rating and 0.250″ quick-connect terminals. It is intended for air handler blower motor control in Carrier-family systems and similar setups, with a likely replacement path sometimes listed as HN61PC003. Best for: Carrier-compatible air handlers needing a straightforward swap. Better for: those seeking a direct OEM-style replacement. Limitation: verify that the coil voltage is 22VDC and the configuration matches your control board connections.
Sonzrod T92P7A22-240 Power Relay
Coil: 240VAC. Contact rating: 30A, DPST-NO (2 Form A). Flange-mount design with 8-pin quick-connect terminals. Best for: high-current HVAC fans, furnaces, and air handlers requiring a robust 240V coil with reliable switching. Why selected: widely compatible with HVAC brands needing a 30A, 240V coil relay. Caution: ensure your control circuit is designed for 240VAC coil operation and confirm mechanical mounting fit in your panel.
Sonzrod T92P7A22-24 HVAC Power Relay
Coil: 24VAC. This is a DPST-NO (2 Form A) relay with a 30A, 24V coil configuration and 0.25″ quick-connect terminals. Best for: 24V HVAC control circuits that need a reliable actuator for blower motors or auxiliary elements. Choose this if your system uses 24VAC controls rather than 240VAC. Limitation: verify coil voltage matches your board’s driver signal to ensure proper energization.
ACDelco Gold 15-50961 Blower Relay
Coil and exact electrical specs not stated in the brief data, but it is positioned as a premium aftermarket blower relay from ACDelco. Best for: those seeking a dependable, widely-supported aftermarket option with professional-grade replacement standards. Caution: confirm coil voltage and form factor to ensure compatibility with your air handler wiring diagram and control board.
Buying Guide: Key Considerations for Air Handler Blower Motor Relays
- Coil voltage and form factor: Match coil voltage (22VDC, 24VAC, or 240VAC) and form (DPST-NO / 2 Form A) to your control board outputs and wiring harness.
- Current rating: Ensure the relay can handle the blower motor’s startup and running current (typical 30A for many HVAC relays).
- Terminal type and spacing: Check for 0.250″ (6.3mm) quick-connect terminals or other connectors used in your unit.
- Compatibility: Verify the part number (e.g., HN61PC002) and whether your unit requires a direct OEM replacement or a compatible substitute.
- Installation precautions: Always de-energize the system, label wires, and document wiring before replacement. If uncertain, consult a qualified HVAC technician.
- Mounting and physical fit: Ensure flange or panel mounting options fit within your air handler cabinet without interference with other components.
FAQ
- What is a blower motor relay in an air handler?
A blower motor relay controls the activation of the blower motor in response to control signals from the thermostat or control board. It switches high current to start and run the blower safely.
- How do I know which coil voltage I need?
Check your control board or original relay markings. Common values are 22VDC, 24VAC, or 240VAC for different systems.
- Can I replace a relay with a different brand?
Yes, if the replacement matches the coil voltage, form factor (DPST-NO / 2 Form A), and current rating. Verify wiring compatibility with the unit diagram.
- Is it necessary to turn off power at the breaker during replacement?
Yes. Always disconnect power before servicing HVAC electrical components to prevent shock and equipment damage.
- What happens if I install a relay with incorrect voltage?
Using the wrong coil voltage or form can prevent the relay from energizing or cause wiring damage and unsafe operation.
