The Thermocouple in John Wood Water Heater Systems
In John Wood water heater equipment, the Thermocouple senses pilot flame heat and signals the gas valve to stay open. John Wood designs their thermocouple components to work with their proprietary technology, including Canadian-engineered tank design optimized for cold BC incoming water, self-diagnostic Honeywell gas valve, powered anode rod, energy-friendly insulation, dual thermostats for consistent output. When this component fails, it can trigger error codes, cause the system to shut down, or result in inefficient operation. Understanding how the thermocouple integrates with John Wood's overall system design is essential for accurate diagnosis and proper replacement. CANRO Heating & Cooling technicians have the manufacturer-specific knowledge to service John Wood thermocouple issues correctly.
