It sounds unbelievable, but furnace technicians often find that the only “repair” a furnace needs is to be turned on. Look for a standard wall switch on or near the furnace—all furnaces, no matter what age or type, have one somewhere. Check the circuit breaker or fuse for the furnace as well. Make sure the front panel covering the blower motor is securely fastened—there’s a push-in switch under it that must be fully depressed for the furnace to operate. 4 / 9.

Essentially, the blower will not turn on. I'm becoming convinced i need to replace my control board, but hoping to be certain. You'll see quickly i don't know much of what i'm talking about, but i'll do my best to give you as much info as i have. It's a ruud gas furnace. When i turn the furnace on, the blower does a quick cycle (letting me know it does function/has power) and the furnace ignites and runs for a minute until the thermal fuse shuts it off, but blower never runs.
When your thermostat is set to auto, your furnace fan should only blow when your furnace is in the middle of a heating cycle. But if it constantly runs (your furance won't won't turn off) regardless of whether your furnace is heating, that’s not normal. First, confirm that your thermostat is set correctly and not calling for continuous heat or forcing the fan to blow nonstop. You can do this by setting your thermostat to a lower temperature than the current room temperature, which shuts down the furnace and prevents the thermostat from calling for more heat. If the furnace was in the middle of a heating cycle, wait for 3 to 4 minutes for the blower fan to stop running.
Are you hearing a popping, pinging or rattling noise coming from your furnace? these could be caused by several issues. Rattling noises are usually related to loose panels on the furnace that need to be tightened. Pinging or popping noises are likely due to the ductwork. It will expand and contract, based on whether you’re heating your house or cooling it.
Most furnaces make some noise as they operate. You might hear clicks when the thermostat reaches a certain temperature and sends a signal to the furnace, and you are likely to hear a “whooshing” noise as the air travels through your ductwork. The blower on some furnaces is louder than others. But some noises can be a sign that something is up with your system and that the equipment needs to be inspected, repaired or potentially replaced. For example, if your furnace is making a knocking noise or the furnace is making a rattling noise, that could be a sign that something has come loose and needs to be tightened or adjusted.
Airflow issues frequently contribute to furnace problems, as dirty ductwork and clogged filters impede the smooth circulation of air. These impediments force the furnace to work harder, leading to strain on components and potential malfunctions. Addressing airflow problems is crucial to maintain efficient heating and prevent further complications in your furnace system.
