Question about Comfortmaker EDM4X48FA 4 Ton Cased Multi-Position Evaporator Coil
It was running fine , then I realized it seemed to be stuck on the " starting the cycle mode" where it sounds like it is running but never kicks in to lighting then blowing hot air. The furnace/AC unit is 3 years old. I turned the thermostat down below the current air temp and the unit clicked like it was going to shut itself off but it is still making the same noise. I shut the unit off at the thermostat , no change ..I shut it off T the breaker and it is still making the same noise. When I opened the unit door the green light was flashing 3 quick flashes then off then 3 quick flashes. It I s 4 am and too early to call my furnace man unless it is an emergency

1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.
