Your low pressure switch may not be functioning right if your furnace inducer motor switches on in high speed and high ignition, then loses speed and shifts into low-fire mode about 30 seconds later.
Your system will demonstrate something’s wrong with a red flash from its indicator light, which it uses to display 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.
