Carrier HN67ER032 Relay
The Carrier HN67ER032 Time Delay Relay is a critical HVAC control board component designed for precise timing sequences in residential and commercial air handling units. This SPDT time delay relay operates on a 24V control circuit, facilitating the necessary lag between the thermostat call and blower motor engagement to ensure optimal heat exchanger temperatures and prevent liquid slugging in cooling cycles. As a genuine OEM Carrier replacement part, the HN67ER032 maintains system impedance and electrical logic integrity, providing a direct fit for Payne, Bryant, and Carrier furnace blowers. The solid-state circuitry is engineered to withstand high-cycling environments, preventing chatter and ensuring reliable contact closure under varying inductive loads. Replacing a faulty HN67ER032 relay restores proper fan-off delays, which is essential for maximizing Sensible Heat Ratio (SHR) and improving overall SEER ratings. This relay utilizes standard 1/4-inch male spade terminals for rapid integration into existing wiring harnesses.
Key Benefits for Technicians- Precise Timing Logic: Ensures accurate blower delay intervals to maximize thermal efficiency and component longevity.
- Direct OEM Compatibility: Eliminates mounting and wiring field-modifications when servicing Carrier blower motor circuits.
- Inductive Load Handling: Robust internal contacts are rated to manage the high inrush current typical of HVAC transformer and motor startup.
- Solid-State Stability: Provides consistent performance across a wide operating temperature range, reducing nuisance service calls.
Is the HN67ER032 cross-compatible with universal time delay relays?
While universal adjustable time delay relays can sometimes be used, the HN67ER032 is factory-calibrated for specific Carrier fan control sequences to maintain the equipment's original engineering specifications.
What are the symptoms of a failing blower time delay relay?
Common indicators include the blower motor failing to start after the inducer or compressor engages, or the fan running continuously even after the thermostat reaches the setpoint.
How do I verify the voltage for this relay during troubleshooting?
Technicians should check for 24VAC across the coil terminals (R and C or equivalent) to ensure the HVAC control voltage is reaching the relay before diagnosing a mechanical contact failure.
