Description
The Trane CNT1704 is a genuine OEM 24-volt pilot relite control designed to maintain safe and reliable pilot flame operation in gas furnaces and other heating systems. This essential control module continually monitors the pilot flame and, if it goes out unexpectedly, automatically sparks a relight — enhancing safety, reducing shutdowns, and helping ensure your HVAC system operates efficiently season after season.
Key Features
- 24 V Pilot Relite Control: Works with standard low-voltage furnace control circuits to detect a lost pilot flame and initiate a relight sequence.
- OEM Quality & Compatibility: Built to Trane factory specifications for reliable performance and a precise fit in compatible gas furnace models.
- Automatic Flame Monitoring: Helps maintain continuous pilot operation, reducing the risk of flame-out shutoffs and improving heating consistency.
- Durable and Compact: Engineered for long life under typical furnace operating conditions and easy replacement during service or maintenance.
- Critical Safety Component: Plays an important role in ignition and combustion safety by preventing unlit gas flow if the pilot goes out.
