A mishap such as a not turning on and off furnace might happen to all existent brands of HVAC appliances, not only Amana furnaces. One common thing is a strong necessity to eliminate the issue soon till none catches frostbite. It’s generally a restricted exhaust causing the vacuum switch to not engage, or possibly a flame roll out switch. If it's a pressure switch error it means the switch isn't closing during the check for air. Could be restricted exhaust, water, or a bad switch. Start troubleshooting. Some flame roll-out switches have a small button in the middle that has to be reset manually. Don’t bypass the safety switches by connecting the 2 wires together. This is not safe. Also not safe to bypass the vacuum switch after the induced draft motor comes on. Could make carbon monoxide- very unsafe. Most likely, either the electrical system providing your furnace’s power has shorted or the power switch has blown. Try resetting your furnace’s circuit breaker. If it has blown, you will need to replace it. Your furnace’s flame sensor monitors the burner, detecting whether a flame is present. If it is either defective or dirty, it will not be able to detect a flame. If dirty, clean the sensor using a fine abrasive pad. If faulty, replace the flame sensor. The furnace’s igniter might either be cracked or faulty. Check the part for cracks, if it is then replace the igniter. If it isn’t cracked, use a multimeter to test for continuity. Hard to test unless you have a meter and have been previously trained so that we strongly recommend calling a professional for safety reasons.
