If you have a gas furnace that is giving you trouble, follow these short tips to ensure you really need a service call.
#1- CHECK THERMOSTAT.
Make sure your thermostat is set on heat and the temperature is higher than the room temperature.
Change the batteries. Even though it doesn’t say “low battery”, the batteries could be weak and not able to make the connection.
Make sure the thermostat is snapped back in position if you try to change the batteries.
#2- CHECK ALL SWITCHES AND CIRCUIT BREAKER
Check your circuit breakers and make sure they are not “tripped”. If one looks like it is in between on and off then turn it to the off position and back on. That resets the breaker.
Make sure all switches are in the up (on) position. Many people have switches either going down into their basement, at the top of the stairs, or before entering the attic. Sometimes the switches are labeled “furnace switch” and sometimes they just look like light switches.
Check the switch on the furnace. Always there is an emergency switch on the unit or on a wall next to the unit. Confirm its up (on).
Try to reset it by turning the switch off, wait a few seconds, and back on.
#3- CHECK FOR BLINKING LIGHT
Newer furnaces have a little window on the cabinet door that you can look through and see a little light. That light will tell you there is power and also will tell the technician a code that will help troubleshoot the problem.
#4- CHECK YOUR FILTER
Make sure your filter is clean or change it. This could cause bad air flow and cause safety’s in the unit to go off.
#5- CHECK CONDENSATE PUMP
High efficient furnaces create condensation. The condensation goes into a pump (little white or black box next to the unit). Confirm no one has unplugged the pump. The pump has a safety in it. If it goes bad or fills up to high it will turn off furnace. If someone did unplug it, plug it back in and the pump should turn on.
