Common Issues with Honeywell Gas Control Valve:

The Honeywell gas control valve is known for occasional issues reported online. However, it’s important to note that these problems are often related to improper installation or environmental factors. The government’s new regulations for backdrafting have led to a lower threshold, causing some units to encounter problems when installed in unsuitable environments.

Installation Tips for Honeywell Gas Control Valve:

To ensure a proper installation and avoid potential issues with the Honeywell gas control valve, consider the following tips:

  1. Ventilation: The vent should have at least 12 inches of rise before the first elbow. If the unit is common vented with a connector rise of less than 3 feet, it’s recommended to use a 4-inch vent instead of a 3-inch vent.

Understanding Honeywell Gas Control Valve LED Indicators:

The LED indicator on the Honeywell gas control valve can help troubleshoot specific issues. Here’s a breakdown of the LED indicators and their meanings:

  • No Flash: Pilot not lit or insufficient power.
  • 1 Flash: Normal operation.
  • 2 Flashes: Thermopile low voltage. Check wiring connections and consider replacing the thermopile.
  • 4 Flashes: Temperature exceeded. Consider keeping the thermostat temperature down to prevent exceeding the limit.
  • 5 Flashes: Sensor failure. The gas control valve must be replaced.
  • 7 Flashes: Gas control valve failure. Replacement is required.
  • 8 Flashes: Power off failure. Reset the gas control valve or consider replacing it if the pilot remains lit.

Steps to Resolve Honeywell Gas Control Valve Issues:

  1. 2 Flash Code: If there is insufficient power to the gas control valve/thermostat, check all wiring connections. If the problem persists, replace the thermopile. Note that the entire pilot assembly must be replaced when replacing the thermopile.
  2. 4 Flash Code: If the temperature has exceeded the limit, the gas valve needs to be replaced. This issue is often attributed to sediment in the tank. Adjusting the thermostat temperature can help prevent exceeding the limit.
  3. 5 Flash Code: A sensor failure indicates that the gas control valve requires replacement.
  4. 7 Flash Code: Overall failure of the gas valve, typically requiring replacement. If you encounter this code and have lukewarm water with the pilot still on, try increasing the temperature setting.
  5. 8 Flash Code: Reset the gas control valve by turning the gas control dial to “off” and letting it sit for one minute. If the pilot remains lit, the gas control valve needs to be replaced.
