Honeywell Q313A1188 Thermopile Generator
The Honeywell Q313A1188 Thermopile Generator is a critical component for technicians servicing self-powered 750mV millivolt gas control systems. This replacement thermopile contains multiple thermocouples connected in series to provide a robust 600mV to 750mV open circuit output, sufficient to operate automatic gas valves without an external power source. Featuring a 35-inch lead length and 2.89 ohms resistance, the Q313A1188/U is designed for high-temperature durability, with a hot junction rating of 1400°F (760°C) and a cold junction rating of 780°F (416°C). This unit includes a 1/2-inch attaching nut and push-in clip for immediate installation in pilot burner models such as the Q314, Q324, Q327, Q377, Q379, and Q382. Professionals often utilize this part to resolve low millivolt output issues in gas fireplaces, boilers, and water heaters where a reliable powerpile generator is required for safety shutoff and main burner ignition.
Key Benefits- Broad Compatibility: Direct replacement for Honeywell models Q313A1022, Q313A1022/U, Q313A1147, and Q313A1188/U.
- Secure Connections: Equipped with spade terminal leads for a tight electrical interface with millivolt gas valves.
- Installation Ready: Includes the 1/2" attaching nut and push-in clip to accommodate various pilot burner brackets.
- High Thermal Tolerance: Engineered to withstand extreme pilot flame temperatures for consistent voltage generation.
- Why is my millivolt system not engaging the main burner? If the open circuit voltage is below 600mV, the thermopile generator may be failing or the pilot flame may not be properly enveloping the tip. Test with a multimeter at the valve terminals.
- Can I use a 750mV thermopile on a 30mV thermocouple system? No. Millivolt systems (Powerpile) require the 750mV output of the Q313A1188 to provide enough current to hold the solenoid and open the valve; a standard thermocouple will not provide sufficient power.
- What does the 2.89 ohms resistance indicate? This specification ensures the internal series of thermocouples is intact; high resistance typically indicates internal degradation or lead damage.
