Some easy fixes for a furnace not blowing hot air include checking the thermostat settings, changing the air filter, ensuring the pilot light is lit, and checking the circuit breaker. If these do not solve the issue, it may be necessary to call a professional HVAC technician for further inspection and repair.
There are several possible reasons why your furnace may be blowing but not producing heat. Some common causes include a malfunctioning thermostat, a clogged air filter, a faulty pilot light, or a problem with the gas supply. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.

There could be several reasons why your furnace is running but not blowing hot air. Some possible causes include a malfunctioning thermostat, a clogged air filter, a faulty pilot light, or a problem with the heating element. It is recommended to check these components and consult a professional HVAC technician for further assistance.
A furnace may be blowing cool air due to issues such as a dirty air filter, a malfunctioning thermostat, or a problem with the pilot light or ignition system. It is best to have a professional HVAC technician diagnose and repair the issue.
There could be several reasons why your furnace is blowing out cold air instead of warm air. Some common causes include a malfunctioning thermostat, a clogged air filter, a faulty pilot light, or a problem with the heating element. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.
If it's blowing intake-temperature air, either you've got the fan alone switched on or the heating part isn't working for some reason. If it's a gas furnace, the pilot light may have gone out, or the gas may be shut off somewhere (at the furnace itself, at the emergency shutoff for the house, or possibly at the main inlet). If it's blowing actually COLD air (colder than intake), then you've probably got central air and you've somehow managed to turn on the air conditioner.

Sorry, but it is impossible to make bedrock in a furnace without using some sort of mod.
A resistance furnace runs on electricity so it will be some type of electrical transformer.
heater, boiler, oven
Most do not. Some may have gears in the fuel pump. A coal fired furnace may have a screw to feed in the coal.
Furnace Purge would involve allowing some minimum quantity of air to flow through the furnace (without fuel) for a specified period of time to remove any unburnt fuel.
