A natural gas and propane burn cleaner than a fuel oil, and most gas furnaces present fewer operational difficulties than oil burners do. In fact, the problems that affect gas furnaces typically involve the furnace's thermocouple, the pilot light, or some component of the electrical system.
Gas furnaces and heaters have control shutoffs to prevent the gas leaks, but they are not fail-safe. If you suddenly encounter the smell of gas in your house, do not turn any lights on or off, and do not try to shut off the gas leading to the furnace. Get out of the house immediately, leave the door ajar, and call the gas company or the fire department to report a leak. Do not re-enter your home until the condition is safe. On some gas furnaces and heaters, a plug-type door covers the pilot light assembly. To gain access to the pilot burner, you can pull the door out of the furnace housing. On other units, you can also remove the panel that covers the pilot and gas burners.
The pilot light controls, reset buttons, gas valves, and thermocouple are usually contained in an assembly at the front of the furnace. The furnace limit switch is located on the plenum (main chamber) or main duct junction on the upper housing of the furnace.
How can a plumber repair the gas? First of all, a plumber will clean the pilot or igniter. A one-minute cleaning will solve 75 percent of burner problems. To get at the ignition system, lift the lid of your stove. Give it a rap with the heel of the hand if it’s stuck. If the stove has sealed burners, identified by the igniter or little nub at the back of each burner, the lid won’t lift.
Secondly, it is important to clean the burner assembly. This might take around five minutes. Clean the burner assembly the same way for both spark ignition stoves and standing pilots. You’ll need a small diameter brush. You can purchase a tube brush from a drugstore. Appliance parts stores will probably have them too. If you have sealed the burners, you’re limited to clean only the burner ports. The other parts are sealed so they won’t get clogged.
Thirdly, it would be wise to check the spark ignition system. You need to ensure that the stove is already plugged in, there is power to the outlet, and the circuit breaker hasn’t tripped. Spark ignition stoves need an electricity to power the igniters. If your oven light turns on, it means that you have the power. In short, the plumber is an expert and professional to do all the plumbing stuff. They will not cause any damage or explosion in your house. You might probably not able to handle it by yourself, so do not need to hesitate to call them before you explode your home.
