More Common Gas Heating Troubleshooting Tips
Find more FAQ's in the menu on the left and at the bottom of this pageHigh Efficiency Gas Furnace Tries to Start - Clogged PVC Pipe Condensate Drain
* If you have a high efficient gas furnace (usually indicated by having 2 to 3 inch white plastic PVC pipe running from the furnace all the way up to the roof or through an outside wall from a crawl space) and it is real cold outside a common issue is having a frozen condensate drain. In this case look outside your home for where the condensate drain is located, many times there is an ice build up around it and this blocks the water from draining properly. You can use a hair dryer or hot water and melt the ice from both outside and inside the pipe and the furnace should start working once the water drains out.

High Efficiency Gas Furnace Tries to Start - Clogged PVC Pipe Gas Flue
* In Southern Idaho we usually do not get much for snow but in the event that we do get a lot of snow and you have a high efficiency unit located in the crawl space with the PVC pipe going out a side wall of the house then check to be sure the pipe is clear from ice and snow, it is common for these pipes to get blocked up by the snow. Just clear away the snow from the pipe. These same types of equipment installed in attics can run into the same issue with frozen condensate drain lines in the attic, this can usually be solved by installing plumbing heat tape.Back to Top
My Furnace only Heats the House for a Short Period of Time and Shuts Back Off
* If your heating system runs the fan, lights the main flame but only heats the house for a short period of time and shuts back off only to restart a few minutes later or it restarts after you turn the power off and back on then the
first thing you need to check is your air filter. If the filter is very dirty this
prevents the system from flowing the proper amounts of air through the heat exchanger and this results in overheating of the furnace. There are safety devices to prevent this and they shut off the furnace until it cools back down.Back to Top
What does the Blinking LED Light Mean on my Gas Furnace
* On newer systems you can usually find an LED light, usually green, on the units control circuit board that is either steady on or blinks. This LED light will indicate the status of your unit based upon if it is steady on or the based on the number of the fast blinks. You can try to de-code these blinks by reading the equipment instructions at the unit or in the manual. Sometimes it will just simply have a steady blink which usually means that the system is trying to start. Usually if it is blinking several times this indicates some sort of fault or failure. What you can try is to reset the control board by turning off the power for a few seconds and then turn it back on, sometimes the system will start working again but most times the system will simply repeat the blinking fault after trying to run. Either way you should have it checked as soon as possible by a qualified service company.
