Trane CNT0696 Relay

The Trane CNT0696 Relay is a specialized 24V DPST Time Delay Relay engineered for precision sequencing in residential and light commercial HVAC systems. This Trane OEM replacement part features a double-pole single-throw configuration designed to manage circuit timing for blower motors and compressors, preventing short-cycling and protecting system components from premature wear. Built to withstand high-amperage draws during startup, the CNT0696 control relay ensures reliable switching within the low-voltage control circuit. When troubleshooting intermittent fan operation or ignition failures in older Trane and American Standard units, this DPST time delay relay is often the primary diagnostic target for restoring optimal operational timing.

• OEM Compatibility: Precision-matched for Trane and American Standard furnaces and air handlers, ensuring seamless integration with existing low-voltage wiring.
• Enhanced Durability: Robust contact design handles high-frequency switching cycles without contact welding or signal degradation.
• System Protection: Integrated time-delay logic prevents rapid cycling, reducing mechanical stress on the compressor and blower motor.
• Direct Fit: Standardized mounting footprint allows for rapid field replacement, minimizing labor time and system downtime.

Common Questions

What are the symptoms of a failing Trane CNT0696?
Common signs include the indoor blower motor failing to start after the thermostat calls for heat or the motor running continuously even when the set point is reached. A faulty time delay circuit often leads to erratic switching or a complete failure to close the contacts.

Can I use a generic DPST relay instead of the CNT0696?
While ratings may appear similar, this OEM relay is calibrated for specific timing sequences required by the furnace control board. Using a generic substitute can lead to sequencing errors or safety lockouts.

What is the coil voltage for this relay?
The relay operates on a standard 24VAC control circuit, typical for most residential HVAC transformers.
