In this guide, we will delve into common troubleshooting steps to help you effectively diagnose and resolve Robertshaw gas valve issues.


Common Gas Valve Issues

Gas valves play a crucial role in the functioning of gas-powered appliances. However, sometimes issues may arise that require troubleshooting. Here are some common gas valve problems:

No Gas Flow

Check gas supply, valve position, and connections for any obstructions.

Pilot Light Won’t Stay On

Inspect the pilot light assembly for cleanliness and proper alignment.

Thermostat Malfunction

Ensure the thermostat is set correctly and functioning properly.

Understanding Gas Valve Components


Main Valve

The main valve is a critical component of the gas valve system that controls the flow of gas to the burner.

Pilot Valve

The pilot valve is responsible for maintaining a small flame that ignites the gas when the thermostat signals the need for heat.


The thermocouple is a safety device that detects whether the pilot light is lit, allowing gas to flow to the burner only if the pilot light is on.

Diagnostic Tools And Techniques

The diagnostic tools and techniques for troubleshooting Robertshaw gas valves are crucial for identifying and addressing potential issues. By utilizing these tools and techniques, service technicians can accurately diagnose and resolve gas valve problems, ensuring optimal functionality and safety. With the use of the right diagnostic tools and techniques, it becomes possible to efficiently pinpoint the root cause of any gas valve issues.

Multimeter Testing

Multimeter testing is an essential diagnostic technique for troubleshooting Robertshaw gas valves. Technicians can use a multimeter to measure voltage, resistance, and continuity, allowing them to assess the electrical components of the gas valve. By conducting specific tests with a multimeter, technicians can identify any faulty electrical connections or components, enabling them to take appropriate corrective actions.

Gas Pressure Check

A gas pressure check is another vital aspect of troubleshooting Robertshaw gas valves. Using a manometer, technicians can measure the pressure of the gas supply to ensure it falls within the specified range. This diagnostic tool helps to identify potential issues such as gas leaks or pressure irregularities, allowing for prompt corrective measures to be taken to maintain safe and efficient gas valve operation.

Visual Inspection Tips

Visual inspection is an important technique for identifying external signs of gas valve issues. Technicians should visually inspect the gas valve for any signs of corrosion, damage, or gas leaks. By carefully examining the physical condition of the valve and its surrounding components, technicians can detect visible irregularities that may indicate underlying problems, ultimately guiding them in the troubleshooting process.

Repair And Maintenance Tips

For effective Robertshaw gas valve troubleshooting, it’s crucial to regularly clean and inspect the valve for any signs of wear or damage. Additionally, avoid neglecting routine maintenance and monitor the unit’s performance for any irregularities to ensure efficient functioning. Regular inspection and care of the gas valve can prevent costly repairs and ensure safety.

Cleaning Procedures

Proper cleaning is crucial for maintaining the efficiency and performance of your Robertshaw gas valve. Follow these cleaning procedures:

  1. Before starting any cleaning, make sure to turn off the gas supply and disconnect the power to the valve.
  2. Use a soft cloth or brush to gently remove any dust or debris from the external surfaces of the valve.
  3. To clean the internal parts, carefully remove the cover of the valve using a screwdriver.
  4. Inspect the components for any signs of dirt or corrosion. If necessary, use a mild soap solution and a soft brush to clean them.
  5. Thoroughly rinse the components with clean water and ensure they are completely dry before reassembly.
  6. Finally, securely reattach the cover and turn on the gas supply and power to the valve.

Replacing Faulty Components

If you suspect that certain components of your Robertshaw gas valve are faulty, follow these steps to replace them:

  • Identify the faulty component by carefully inspecting the valve and its functioning.
  • Refer to the manufacturer’s instructions or user manual to understand the replacement procedure specific to your model.
  • Obtain the correct replacement part from an authorized dealer or reliable supplier.
  • Once you have the new component, carefully remove the old one using appropriate tools.
  • Ensure that the replacement component fits properly and securely into place.
  • Tighten any necessary screws or connectors and double-check that the installation is correct.
  • Turn on the gas supply and power to the valve to test its functionality.

Regular Maintenance Schedule

Maintaining a regular maintenance schedule for your Robertshaw gas valve is essential for optimal performance. Follow these guidelines:

Inspecting for leaks or damageMonthly
Cleaning external surfacesQuarterly
Checking and cleaning internal componentsBi-annually
Replacing worn-out or damaged partsAs needed

Adhering to this maintenance schedule will ensure that your gas valve operates efficiently and minimizes the risk of unexpected issues.

When To Call A Professional

While troubleshooting a Robertshaw gas valve on your own can save you time and money, there are certain situations where it’s best to call a professional. Handling complex valve malfunctions, ensuring safety concerns are addressed, and recognizing the limits of your own DIY experience are important aspects to consider.

Complex Valve Malfunctions

If you encounter complex valve malfunctions with your Robertshaw gas valve, it is wise to seek the expertise of a professional. These professionals have in-depth knowledge and experience in dealing with complicated issues that may arise. Complex malfunctions could include problems such as valve leakage, inconsistent gas flow, or incorrect pressure regulation. Trying to solve these issues without proper training and understanding can worsen the problem and potentially lead to more costly repairs.

Safety Concerns

Ensuring safety should always be a priority when it comes to gas valve troubleshooting. If you notice any signs of safety concerns such as strange odors, gas leaks, or unusual flame patterns, it’s crucial to call a professional immediately. Safety issues associated with gas valves can be dangerous and potentially lead to fires or gas poisoning. Professionals have the necessary tools and expertise to identify and resolve safety concerns, providing you with peace of mind and ensuring the safety of your home and family.

Inadequate Diy Experience

Recognizing the limits of your own DIY experience is essential in gas valve troubleshooting. While some minor issues can be resolved by following troubleshooting guides or tutorials, tackling larger and more complex problems without the necessary experience and knowledge can be risky. Gas valves are intricate components that require expertise to handle effectively. Professionals have the training and experience to diagnose and address problems efficiently, ensuring that your gas valve operates effectively and safely.
