Your low pressure switch may not be functioning properly if your furnace inducer motor begins in high speed and high ignition, then weakens and shifts into low-fire mode about 30 seconds afterward.
Your system will communicate something’s amiss with a red flash from its indicator light, which it uses to exhibit error codes. It has this red light to flash code, like Morse code.
You may notice fast flashes or an alternating slow flash as it announces a fault code.
