Please refer to the diagram below:

WHY DO I NEED TO BYPASS THE OVER-TEMP SENSOR?

When troubleshooting your L7 with our Technical Support, sometimes they may ask you to "Bypass the Over-temp sensor".

Why? 

  • If the over-temp sensor is faulty, it may prevent the unit from igniting. (We can confirm that the part is faulty by bypassing it)
  • If the unit ignites with the sensor bypassed, then it is the sensor that is the problem. 
  • The sensor is a fail-safe device. Without it, your unit would go beyond the limit of heating and it would cause it to overheat. The over-temp sensor stops this from happening.
