Furnace flame rollout safety


This is a picture of a flame rollout safety switch it will trip at a set temperature. The temperature set point of the rollout is designed to open when the flame is coming out the front of the burners

  • Possible heat exchanger has a hole or big crack.
  • Another possible cause is a combustion air intake pipe getting a plugged screen, Which will cause the room to work in A negative air pressure. Then air will be pulled in through the exhaust vent pushing flames out of heat exchanger and tripping the switch.

Between the wires the switch has a resettable button, but the cause of the problem should be found before leaving furnace. Never jump safety switch as it could cause property damage.

      Anytime a rollout is reset make sure the reason for the rollout is addressed or it will keep giving you problems. It is good I was able to help you through this challenge.
