💡 How do you know when a residential furnace control module needs swapping?
Your heating loop hits the right temperature but the indoor blower stays quiet or the flame sensor throws constant lockouts. Installing a direct replacement pcb handy fixes those weird timing glitches fast. Watch for these telltale symptoms:
- Repeated ignition retries that drain propane before reaching target heat levels
- Erratic fan speed changes that cause whining noises near the air handler
