Gas furnaces tend to offer less problems than other heaters, although there are still a few problems that may arise. No matter what you think the problem may be, if you ever smell gas you should immediately vacate the home and call the professionals. Other than a leak, gas heating repair should be fairly simple to complete. Troubleshooting If your gas heater isn't working, there are a few things that you can look into that may offer easy fixes. If the furnace won't run, the pilot light may have gone out. Simply relighting the pilot will solve this problem. If there isn't any power at all, you may have blown a fuse. Check the circuit breakers and restore if needed. If heat is being produced, but not enough to heat the home, several items may be dirty or clogged. The filter can easily be cleaned or replaced if necessary. If the blower is clogged, you can clean out the blower assembly. A blower belt that is loose or broken can also be adjusted or replaced. If the burner is dirty, however, you will need to call the professionals. Thermocouple The thermocouple is located near the pilot light burner and will act as a safety device that shuts the gas off if the pilot light goes off. Often a problem with the heat leads to the thermocouple. If the pilot light continues to go out, the thermocouple is most likely faulty and will need to be adjusted or replaced. To adjust the thermocouple, use a wrench to tighten the nut slightly without applying too much pressure. If this doesn't solve the issue, you will need to replace it. There are many places for you to find the proper instructions on how to replace this part, though you should call professionals if you're unsure of your capabilities. Heating repair can be simple if you understand the parts involved in your furnace.
