How do you get your gas furnace blowing tepid air again?
There are several reasons that could make your gas furnace blow chilly air, and to make it blow moderate air again, you will need to troubleshoot your gas furnace; Begin by checking your temperature control and make sure the setting is set on “auto” and not “on.” Also, check and set the temperature to 5 degrees above the room temperature, however this will help start the gas furnace. Your temperature control should also display the right tim+e. You will also need to trace the wires from the temperature control to see if there are any wire breaks; If you find a wire break, splice them together and wrap them with electrical tape. Check shut-off switch and circuit breakers as oil furnaces have safety features that switch the component off when it gets hot… Look for a correct wall switch near the gas furnace and fully depress it to operate again. If you have an oil-fired gas furnace, you may need to refuel the burners to light and produce heat. A gas furnace with dirty air filters may also shut down as the blower will not have enough air, which causes the component to overheat, shutting down the burner. Change the air filters and turn the component on again. You should also check the gas valve to see whether it is on or off. Turn it on if it is facing the off position. A blower motor that is not closed officially will not turn on as the safety unit will prevent the gas furnace from turning on. You will need to shut the blower panel officially for it to resume working.
