Every time your thermostat calls for heat, the furnace runs a fixed checklist. The inducer motor starts and proves draft by closing a pressure switch, the hot surface igniter heats up, the gas valve opens, the burners light, and the flame sensor confirms there is fire. Only after all of that does the blower start pushing warm air into the house. Finding the step that fails is most of the job. Around Odessa, TX, the usual failure points are an oxide-coated flame sensor, an igniter cracked by years of heating and cooling, a pressure switch that stays open because of a weak inducer or a clogged condensate trap on a high-efficiency unit, and control boards with burned relays. Any one of them halts the startup, and from the hallway they all look alike.

- Short cycling every few minutes without reaching the setpoint
- Repeated shutdowns just seconds after the burners light
- Squealing or grinding from the blower compartment
- Booming or banging at light-off from delayed ignition
- A flame that burns soft and yellow rather than steady blue
- The furnace clicks and glows but the burners never light
- The blower runs constantly but the air never warms
