There could be several reasons why your furnace blower is not turning on when the heat is activated. Some common causes include a faulty thermostat, a malfunctioning blower motor, a clogged air filter, or a problem with the electrical connections. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.
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.

This means there is a blower attached to the system that forces the heat into the home.
There should be only one blower to move the air. The unit will have a coil for cooling and a heat exchanger.
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.
A furnace spark ignitor works by creating a spark that ignites the gas in a furnace. When the ignitor is activated, it generates a high-voltage electrical spark that ignites the gas, allowing it to burn and produce heat for the furnace. This process is essential for starting the heating cycle in a furnace.
Yes, you can melt the heat exchanger and start a fire that way

Heat from burning fuel warms the walls of the firebox section of the furnace. When the temperature is raised to a certain degree, the furnace blower will kick in. Warm air then travels through the furnace ducts and out to the rooms of the house.
In an electric furnace, a fan relay typically changes the blower speed to a lower setting for cooling. This reduced speed helps to circulate air more gently, allowing for better heat dissipation and preventing overheating of the furnace components. By operating at a lower speed, the blower can provide effective cooling while maintaining comfort in the surrounding space.
The heat relay needs to be activated by a vaccum switch. On my van the fix was to replace the vaccum line to the relay which allowed the relay to allow heat to travel to the blower.
