Within yourheating and coolingsystem, you have a variety ofHVAC partsthat make up thecontrols。Here we offer all the control parts you need for bothHVAC applications。Choose from among the following product categories:
A furnace control board also referred to as anintegrated circuit ignition control systemcan be thought of as thebrain许多模式rn furnaces. This control system controls many of your furnace’scomplex and sophisticated processesand also has to ability torun self-diagnosticsandprovide repair codessimilar to how you can run a diagnostic on your automobile’s computer. The control board is constantlymonitoring your furnace’s operation。Many control boards are set up so you can find them in the blower compartment of the furnace with a 3-5 Amp fuse protecting the board from a short.
Control boards arealways found on high-efficiency furnacesthat rely heavily on these complex and sophisticated operations to reach their high AFUE ratings of over 90%. When you need a replacement part, you want a quality solution that will last. Here are two of our most popular control boards:
One of the most basic controllers for a furnace is the gas control valve. Gas valves are designed tomanage the flow of combustible gas to a furnace or water heater。换句话说,阀门负责吃晚饭plying the furnace or water heater with gas once they’re ready for combustion. Because gas valves areautomated, they can alsoshut themselves off when the burners go out。
Gas valves do not work independently. Theyrely on input from the thermostat and thermocouple。The thermostat is the manual control that allows the user to manage the temperature within a room or home. The thermometer links a wire to the gas valve to let it know when gas needs to be turned on due to a change in temperature. The thermocouple is steel with a protective tube that contains two metal strips that are welded together. The rear of the tube contains an insulated wire that runs to the gas valve. The gas valve itself connects directly to the gas supply tank of the furnace and has two integrated outputs: one leading to the pilot light, the other to the burners.
Gas valves are one of the more dangerous controllers because aleaky gas valvecould meancarbon monoxide poisoningin the worst case scenario. If you smell gas or suspect your gas valve has a leak, install acarbon monoxide detectorthat will alert you of the problem. You may also want to use asoap solutionin a spray bottle and spray the valve. If a leak is present, the solution will begin to bubble from the gas. Even if you later determine the valve isn’t leaking, it’s better to be safe than sorry.
Relays play an important role for many appliances where there is an electronic control used to turn on something like a motor or light. Whether for your furnace or water heater, relays work by taking asmall amount of powerfrom an electromagnet andactivating a devicethat is able toswitch on a much larger amount of power。
If your relay fails, you won’t be able to run your HVAC system. Even if you are able to with a bad relay, your system will be much less efficient until the relay is repaired or replaced.
Transformers are tools that are used totransfer electricity from one circuit to another, usually with a change in voltage. Transformers are common components used to run electric appliances such as your furnace or water heater.
Transformers work with AC (alternating current) and are important because theyallow electricity to be transferred efficiently。Some transformers, such as those used in televisions or stereo systems, require high voltages, while others, such as doorbells and thermostats, require low voltages.
Without a properly working transformer, youwon’t be able to operateyour heating and cooling systems very efficiently, if at all. If your transformer fails, a discount replacement here is a great way to save time and money.
