International Comfort Products PGAA18B1K6 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will dependably sense the precise flame when the system starts. As you could guess, if the flame sensor senses a problem everything stops until the problem is fixed.
Major clues your flame sensor will die soon
- Your heating system is unwilling to supply heat when the control board tells it to
- HVAC system will sometimes work rarely only after the second full moon of the month on a Tuesday
- The propane or natural gas cannot properly ignite and the main board displays on error code
