Furnaces can sometimes give you head aches, especially if it's cold
outside and you need it more than ever. To make sure you don't need
furnace repair services on a winter day, save yourself some time and
money and learn how to repair your furnace and keep it in a good
First of all, here are some of the major causes you might need 'furnace
repair services' (http://jonesheatingandac.com /): if you have a gas
furnace or heater your problems might involve the thermocouple, the
pilot right or some component of the electrical system. In order to get
access to the pilot burner you have to pull the door out of the furnace
housing or, depending on the situation, remove the panel that covers the
pilot and gas burners. In an assembly at the front of the furnace you
should be able to find everything you need to start your repairs: the
pilot light controls, reset buttons, gas valves and the thermocouple.
If your gas furnace just won't run, check for blown fuses or tripped
circuit breakers at main entrance panel, at separate entrance panel, and
on or in furnace and try to restore the circuit. If it's still not
receiving power then it's time to get some professional repair services.
Also, make sure the the gas valve is fully open and it's receiving fuel.
While you're here, check for gas leaks. Here's what you need to do: stir
up a mixture of liquid detergent and water and paint this mixture on the
gas supply line along its connections and valves. If you have gas leaks
then the soapy water will bubble. To repair it. Try tightening the
leaking connection with a pipe wrench, but be careful not to
over-tighten the connection.
If there's not enough heat, maybe the thermostat is set too low or you
need to clean or replace the filter. Also make sure all registers are
open, or aren't blocked by tugs, drapes or furniture. However, if the
burner is dirty you need professional furnace repair service. If you
need to replace a thermocouple here is what you need to do: Unscrew the
copper lead and connection nut inside threaded connection to gas line.
Under the mounting bracket at thermocouple tube, unscrew the bracket nut
that holds the tube in place. Then insert the new thermocouple and be
sure the steel tube is up can the copper lead is down. Under the
bracket, screw bracket nut over tube. Push the connection nut to
threaded connection where copper lead connects to gas line. Make sure
connection is clean and dry and then tightly screw nut into place, but
do not over-tighten it.
