1) This winter, your stove and boiler will operate safely. Every home is heated with natural gas. When adjusting the furnace, our engineers thoroughly inspected the furnace to check that the chimney was not clogged by checking the draft of the stove and there was no safety problem in the winter. We will check your heat exchanger so that the air in your house will not mix with combustion products. I want to confirm that there is no danger of carbon monoxide leaking or fire

Your stove is built with various safety devices to ensure the safety of your home and heating equipment. One of these safety mechanisms is a limit switch. The limit switch is part of the blower assembly, but it is also part of the overall control system. So, if you have problems with your limit switch, your furnace may experience operational problems. In order to learn more about Hamilton's furnace limit switch, it is important to understand what it means and how it works.

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:

Many safety circuits are used to ensure safe and proper furnace operation. These circuits control potential safety problems and serve as inputs for monitoring and diagnosing abnormal functions. These circuits are continuously monitored by the integrated control module during operation of the furnace. The pressure switch is normally open, and the switch operates with negative air pressure. They monitor the airflow (combustion air and flue products) through the heat exchanger through a pressure plug in the draft fan. These switches prevent the flow of heat through the heat exchanger (combustion air and flue products).
