When the furnace works but heat doesn’t get through
IF YOUR OIL BURNER or gas furnace is functioning, but heat is not being delivered to the rooms, there is a malfunction in the delivery system. Let’s run down each of the delivery systems to see what you can do to overcome the problem, and at least get some heat into the house.
Steam system—Check the boiler gauge. A burner will shut off automatically if the water level in the boiler gets below a certain level.
Hot-water system Inspect the circulator. One that needs lubrication will not circulate hot water although the burner will continue to operate. Caution: Lubricate the circulator only with the grade of oil and/or cup grease recommended on the instruction plate attached to the circulator’s body. Any other type may cause a complete breakdown.
If the circulator has stopped working whether for lack of lubricant or some other reason, press the reset button on the device one time only. If there is no reset button, slap the housing with your hand. A circulator will not deliver heat if one of its couplings is broken. However, the unit will continue to run, so put your ear close to the housing and listen for a sharp, rapping sound.
You may be able to repair the break temporarily. Remove the access cover. If you can get at the broken coupling, wire the broken cross-pieces together. If you cannot repair the circulator, but the burner is operating, you should be able to get some heat through the house. Most hot-water systems have a flow valve on the water line that runs from the furnace to the heat-radiating components. Open the valve. This will feed hot water through the system by gravity.
Important: Don’t forget to close the flow valve after the circulator has been repaired.
Forced-air systems One reason for a reduced heat condition in a forced-air system is a clogged air filter. If you have a spare around, install it. If not, remove the old filter (some furnaces have more than one), take it out-of-doors, and knock it against a hard surface to loosen dirt.
Another reason for little heat delivery is a broken blower-motor belt. The best solution is to replace the belt, so you should keep a spare on hand. You can buy a belt for your blower motor from a hardware store or gasoline station. Make sure it is the right size. Place the belt on the blower-motor pulleys and tighten the adjusting nut, which is usually found behind the motor, until the belt has about 1/2-inch free play. If you do not have a spare belt, try wrapping some strong rope around the pulleys as a temporary measure. A final reason for failure of a forced-air system to deliver heat is a short in the blower motor. A short is indicated by on-off cycling of the motor in short spurts or complete refusal to run. Shut off the switch controlling the blower motor and remove all filters from the furnace. Some hot air will rise and permeate through the ducts to the registers so that minimum fort may be attained until a service technician arrives.
