To troubleshoot a furnace that runs for 5 minutes and then shuts off, check the air filter for blockages, ensure the thermostat is set correctly, inspect the flame sensor for dirt or damage, and make sure the exhaust vent is clear. If the issue persists, contact a professional HVAC technician for further diagnosis and repair.
There is a delay on the fan to allow the furnace to get hot so as not to blow cold air into the home at start up. There is also an `OFF` delay, where the fan runs for a minute or so after the flame shuts off. This is to cool down the furnace.
The furnace runs, shuts off, and starts again to maintain the desired temperature in the house. When the temperature drops below the set point, the furnace turns on to heat the air. Once the temperature reaches the desired level, the furnace shuts off to prevent overheating. If the temperature drops again, the furnace will start up to maintain the set temperature.
It might be on energy saver mode!
mine did the same thing i replaced the crank sensor and it runs fine
96 olds 88 runs for 20-30minutes shuts off wait 10 minutes starts up
an electric furnace runs off of 208/230 Volts while a typical gas furnace runs off of 120 also a gas furnace will have a valve for the gas relay where the gas enters the furnace.

why China still has so many poor people ?
have baseboard heat boiler runs off furnace want to shut off furnace to save oil will it hurt anything
The water being held in the water tank when the furnace shuts off is at a set temp, the water tank hopefully is insulated, as time passes, the water temp has to drop because the furnace has not come on to maintain the set temp, also the controller could be faultly that controls the water temp for the hot water heater, the only time you have hot water is when the furnace runs.
i just read that the idle air control valve can stick. possibly its that.
