The heat it making the duct expand
To turn off the furnace in your home, locate the power switch or breaker for the furnace and switch it off. This will stop the furnace from running and producing heat.

A heat pump will do this, a furnace should not. Are you sure you have a furnace?
The furnace lights up and then goes out because it is designed to ignite the fuel to produce heat, but if there is an issue with the ignition system, fuel supply, or airflow, the furnace may not be able to sustain the flame and will shut off as a safety measure.
If the pilot light goes out on a furnace, the furnace will not be able to ignite and produce heat. To relight the pilot light, you can follow the manufacturer's instructions provided in the furnace manual. Typically, this involves turning off the gas supply, waiting for the gas to dissipate, and then using a long lighter or match to relight the pilot light.
that noise is a lose damper that is on the collar that conects that duct to the plenum. that duct goes into a big box. right before it goes in there is a collar. it may be taped up so feel for a wing nut under the tape.this nut controls a metal disc that controls the air flow through each duct.that nut came lose you have to tighten it up and the noise will stop. Answer Another cause for the creaking could be as simple as the metal of the duct expanding with the heat and rubbing against a ceiling, floor stringer, stud or wall opening somewhere within the first 10-15 feet of where it comes off the furnace. This creaking is also a common problem with baseboard hot water heating systems where the copper pipes come up through the floors and creak as they heat and expand. To repair the problem, turn up your thermostat and then stand in the area of the furnace and wait for the creaking to start so you can see where it is happening. Then use a piece of mineral wool or other heat resistant material that is soft and non-abrasive to put between the duct and where it is making contact.
Your furnace blower may not be shutting off and not producing heat due to issues with the thermostat, the blower motor, or the furnace's control board. It is recommended to check these components and consult a professional HVAC technician for further diagnosis and repair.
The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace.
This vacuum is typically used to heat up metal. A vacuum furnace can reach a temperature of over 2,500 degrees. This furnace heats up fast but can cool itself off even faster.
The steps involved in furnace heat exchanger replacement include turning off the power to the furnace, removing the old heat exchanger, installing the new heat exchanger, reconnecting all components, testing the furnace for proper operation, and ensuring everything is working correctly before turning the power back on.

thermostat is commonly used to regulate the heat of a furnace. It can programmed to maintain a desired temperature by turning the furnace on or off as needed. Some thermostats have additional features such WiFi connectivity, smart home integration, and scheduling options.
