Lennox 22J53 Relay
For mid-to-lower sequence staging in electric furnaces and air handlers, the Lennox 22J53 Relay is the industry standard for managing high-amperage heating elements and blower motor timing. This genuine OEM sequencer (lower seq) relay operates on a 24V control circuit, providing critical load management to prevent simultaneous activation of multiple heat strips. By utilizing precise time-delayed switching, it staggers the electrical draw, effectively protecting the circuit breaker and internal wiring from high-current surges during a call for heat.
Built for compatibility with residential and light commercial Lennox units, this electric heat sequencer features a thermally actuated bimetal disc that ensures reliable contact closure and opening even in high-ambient environments. With a 30-amp switching capacity and UL/CSA listing, the 22J53 provides the staged heating control necessary to maintain consistent airflow and system efficiency. Whether used in auxiliary heat applications for heat pumps or primary electric furnaces, this 24V furnace sequencer ensures the blower runs through the proper cool-down cycle to dissipate residual heat from the furnace cabinet.
Key Benefits for the Contractor- Precise Load Staging: Effectively manages the sequential operation of heating elements to prevent electrical overloads.
- OEM Integrity: Direct replacement for Lennox 22J53 and 22J5301, ensuring exact mounting and wiring alignment for faster installs.
- Thermal Reliability: Engineered with bimetal-actuated timing to provide consistent ON/OFF delays across a wide range of temperatures.
- Heavy-Duty Contacts: Rated for up to 30 amps at 250V, designed to handle the high-draw requirements of electric resistance coils.
- Blower Timing Control: Integrates fan delay functions to ensure the blower reaches speed before elements energize and remains active during the cool-down phase.
How do I confirm the 22J53 is failing?
Technicians should check for 24VAC at the heater coil terminals. If control voltage is present but the bimetal disc fails to warp and close the line-voltage contacts within the specified timing window (typically 30-90 seconds), the internal assembly is compromised and requires replacement.
What is the difference between a "Lower" and "Upper" sequencer?
In multi-stage systems, the "Lower" sequencer (like the 22J53) often handles the initial stages and fan control, while the "Upper" sequencer manages subsequent heat strips. This prevents all coils from hitting the line at once.
Can I use this relay for hydronic air handlers?
Yes, it is frequently used to coordinate the hot water pump and the blower motor, ensuring the coil is sufficiently heated before the fan begins circulating air.
