High Limit Sensor
This High Limit Sensor is a foam pad that attaches directly to the pc board and folds under the control box, laying directly on the heater tube. Be careful when trying to unplug this sensor. The original design was soldered to the pc board. If you pull it off, you may need to buy a complete new board. Please call if you have any questions before testing this sensor.
