Sequence of Operation – Gas Furnaces

Understanding the operating sequence of the gas stove saves time and expense for troubleshooting the phone. We watched over and over again that engineers ordered several parts to repair the gas stove. Has the gas valve, control panel, igniter, limit switch failed at the same time? It may not be the case. You may laugh, but we regularly receive orders for these parts. The order of operations varies by type and brand. In most cases, however, the manufacturer entered a hot surface or direct spark ignition in the following order:

Even if the deflector is on, if the high temperature igniter does not shine, the pressure switch may be inappropriate or the ventilation motor may not be moving enough air (the blower duct is blocked and the blower Will stop)

In this case, knowing how the stove works will show you what happened in the first 5 minutes of the service call.

Gas furnace operation order - Currently, there are various kinds of electronic ignition type high efficiency gas furnace. Some are owned by different manufacturers. One manufacturer then uses the other manufacturer's controller to control the electronic ignition portion of the gas stove. Trane gas stove is an example of a company that manufactures its own electronic ignition gas control device for that furnace. Therefore, when troubleshooting an electronic ignition gas stove, it is necessary to understand a series of operations. It is particularly suitable for all kinds of electronic ignition system. You also need to understand how the controls work. A good engineer can find basic problems in a matter of minutes by walking to the electronic ignition gas stove. Please refer to this article on the operation sequence of electronic ignition gas furnace.

Among the different types of electronic ignition gas furnaces are direct combustion gas furnaces and indirect gas combustion gas furnaces. Indirect gas stoves use indicator lights. Direct fire type gas stove will start ignition of main burner without indication light. The key to both systems is that each electronic ignition system has its own way to prove fire or prove there is fire. In the absence of a fire, the system is shut down so that no gas is injected into the space, which may be very dangerous.
