Carrier 38H Flame Sensor
A flame sensor is a vital part that can sense the correct flame in accordance with the initial ignition sequence. Due to safety concerns, if the flame sensor senses a problem the gas valve is shut off and the system halts until that particular problem is fixed.
What are some indications that my flame sensor is in need of a replacement?
- The type of gas you use has problems trying to start an ignition sequence and shuts off
- System starts rarely at midnight, but only after the new moon following the fourth Monday of the month
- Your system refuses to produce any heat when you crank the thermostat up
