Sep 17, 2023 · Step 1: The furnace starts by receiving a call for heat from the thermostat. Step 2: The control board initiates the sequence of operation and sends a signal to the combustion air intake damper. Step 3: The combustion air intake damper opens to allow fresh air to flow into the furnace.

Sep 20, 2023 · A gas furnace typically follows the following sequence of operation: The thermostat detects that the indoor temperature is lower than the desired set temperature. The thermostat sends a signal to the furnace control board. The control board initiates the combustion process by turning on the gas valve.
Then, the furnace checks the safeties to make sure ignition is possible and safe. If all systems are a go, the inducer motor comes on and clears a path for the exhaust. The furnace then proves that the path for the flue is clear, and a pressure switch closes upon sensing a pressure differential. The miracle of ignition comes next.
Furnace Sequence of Operation – Short 137. In this short podcast episode, Bryan goes over the basic gas furnace sequence of operations. There are a few variations, but the sequence of operations tends to stay consistent across most furnace types. First, a W call from the thermostat calls for heat. The circuit board will then assess the ...
Jason Obrzut comes on the podcast and talks us through his furnace sequence of operation training: “Take It Slow, It's Gonna Blow!”. There are 6 main steps in Jason's furnace sequence of operation training. The phrase, “Take It Slow, It's Gonna Blow!” should help you remember the sequence (Thermostat, Inducer motor, Safety switch ...
