Deciding When It’s Time To Replace a Gas Valve on a Furnace
Fellsmere, FL, homeowners don’t need to turn on their furnaces often. Temperatures in the city, located in the Sebastian-Vero Beach Metropolitan Statistical Area, typically stay in the 70s, 80s, and 90s throughout the year. The only exception to this is from December through March, when temperatures drop into the 50s at night.
On colder nights, some homeowners start their furnaces to take the edge off the chill in their houses. Those with gas-powered furnaces rely on gas valves to regulate the flow of natural gas to their heating systems.
These valves usually won’t present homeowners with problems during the first decades of their heating systems’ lives. However, they will eventually fail, and when they do, they will start to show signs suggesting homeowners must determine how to replace a gas valve on a furnace.
Here are signs that you should strongly consider replacing the faulty gas valve on a furnace:
- Your furnace isn’t turning on
- It’s heating the rooms in your home unevenly
- Its flame has turned yellow or orange rather than blue
In rare instances, you may even smell natural gas leaking into your home with a distinct odor similar to rotten eggs. In this case, you should evacuate your home and worry about replacing the malfunctioning gas valve for a furnace later.
Taking the Correct Steps During Furnace Gas Valve Replacement in Fellsmere, FL
Replacing a furnace’s old gas valve isn’t the most challenging heating repair, but it’s also not a task you should undertake if you don’t have experience working on a heating system.
Still, it’s important to know how to replace a gas valve on a furnace in Fellsmere, FL. This is how the process will play out.
Preparing To Replace a Furnace’s Gas Valve
Before replacing a gas valve, a heating system technician will always take a series of gas valve safety precautions. They will:
- Perform furnace gas valve troubleshooting to identify the issue
- Turn off the gas before replacing a faulty gas valve
- Shut off the electricity to the furnace
If they fail to follow the proper gas valve shut-off procedure, this job could become significantly more hazardous.
Disconnecting the Old Gas Valve on a Furnace
Once a technician is sure the gas and electricity to a furnace are off, they will disconnect the old gas valve. This requires them to take the following steps:
- Locate the valve
- Use a wrench to remove the gas supply line from it
- Remove any electrical connections
- Unscrew it
The valve connects to either a furnace manifold or a burner assembly. Removing it creates space for a new one.
Getting Ready To Install a New Gas Valve on a Furnace
A technician should not immediately connect a new gas valve to a furnace in Fellsmere, FL.
Instead, they must prepare for it by inspecting the gas line and removing blockages, if necessary. They must also add pipe sealant or Teflon tape to the threads of a new valve.
Installing a New Furnace Gas Valve
As long as a technician has properly prepared the furnace, it will finally be time to install a new gas valve. To do this, they must:
- Attach the new gas valve to a furnace and tighten it
- Connect the gas supply line to it
- Attach electrical connections to it
From there, they can turn the electricity and gas back on and test the new valve to ensure it works. Your furnace should start running like usual again.
