One of the most important components of a house, especially to those who experience winter every year, is the furnace. Furnace provides warmth when we couldn’t get it anywhere, which is during the desolately cold winter season. But like all systems and machines, the furnace is also subject to wear and tear, and it can become faulty over time.
A faulty furnace can be very troublesome, especially if gets bad in the middle of the winter season. But in every problem there is a fix, so does with some of the parts of a furnace. Equip yourself with knowledge and know the basic troubleshooting for your Furnace.
1. Pilot Flame
A furnace that is in good condition will only have blue flames, and its height should be around 2 inches high. If you notice that there is a yellow colored flame or its height is shorter than it should be, then there might be a problem with your burner. To adjust it, seek for the pilot assembly and find the gas valve and screw it tighter. Do not confuse the pilot flame from the main burners, if the main burners are faulty, contact professionals, click here.
2. Gas Leaking
One trouble that you should always pay notice off is gas leaking because if left unaddressed, it could cause fire related accidents. You can usually notice if there is gas leaking by simply using your power of smell.
But if you aren’t sure about smelling leaked gas or other substances, you can concoct the solution of water and liquid detergent. Apply this solution to the valves, which is the connection point, and where leaks may occur. If the solution produces bubbles, then a gas leak may be apparent. Use a pipe wrench and try to tighten the valves. If the valves produce bubbles after you tighten it, then you should call professionals to fix it completely.
The thermocouple is a device that is connected with the pilot flame. The thermocouple has an important safety function; it shuts off the gas that is coming in if the electric igniter doesn’t function or if the pilot burner is not working. One indication that your thermocouple may be damaged is if the pilot burner is not producing flame consistently.
To troubleshoot your thermocouple, find the thermocouple nut and use a wrench to tighten it. Make sure not to use too much force because the nut may be broken, just tighten it up slowly. After doing this, try to ignite the pilot flame again, and if it still does not produce consistent flame, consider replacing your thermocouple entirely.
Dirt and dust are one of the main enemies of your furnace, and the component it directly affects is your furnace filter. The best way to protect your filters is to clean your furnace regularly. But through time, the filter would accumulate dirt and dust that would render it unfit for function. To check your filters, take it out in a well-lighted surrounding, and see if its surface is cloggy. If it does, it is better to replace it.
