Product Description
The Braemar Wall Furnace Heater Automatic Over Heat Switch (130°C), Part Number 628646, is an important safety component in Braemar wall furnace gas heaters. It is designed to monitor the internal temperature of the heater and automatically shut down the system if it exceeds a safe operating temperature. This helps to prevent overheating, which could lead to damage or potential hazardous situations.
Key Features of the Braemar Wall Furnace Heater Automatic Over Heat Switch (130°C):
-
Overheat Protection:
- This automatic overheat switch is set to activate at 130°C, a critical temperature point. When the internal temperature of the heater exceeds this threshold, the switch will automatically shut off the heater to prevent overheating and potential damage to the components.
-
Safety Mechanism:
- The primary role of this switch is to enhance safety by preventing the gas heater from operating in unsafe conditions. If the system is overheating due to a malfunction, blocked vents, or a buildup of heat, the switch will stop the heater from running until the issue is resolved.
-
Compatibility:
- The Braemar Automatic Over Heat Switch (PN 628646) is specifically designed for use with Braemar wall furnace heaters. It is a direct replacement for the original part in the system, ensuring that the heater maintains its safety standards and optimal performance.
-
Temperature Regulation:
- This switch helps to regulate the heater’s internal temperature by cutting off power to the system when the threshold is reached, thus preventing further temperature rise and possible damage.
-
Automatic Reset:
- Once the heater cools down to a safe operating temperature, the overheat switch will automatically reset, allowing the heater to function normally again. However, if overheating occurs frequently, it may indicate a deeper issue within the system that requires attention.
Installation of the Braemar Wall Furnace Heater Automatic Over Heat Switch (130°C):
-
Turn Off Power:
- Before working on your Braemar wall furnace heater, ensure that the gas supply is turned off and the electrical power is disconnected to avoid electrical or gas hazards.
-
Locate the Over Heat Switch:
- In most Braemar wall furnace heaters, the automatic overheat switch is located near the heat exchanger or within the heating chamber. You may need to remove the front panel or access cover of the heater to access the switch.
-
Remove the Old Overheat Switch:
- Disconnect the wiring from the old overheat switch and remove any mounting screws or clips holding it in place. Carefully remove the switch from its position.
-
Install the New Overheat Switch:
- Install the new Braemar overheat switch in the same location as the old one, ensuring that it is securely mounted. Reconnect the wiring to the terminals of the new switch, making sure all connections are tight and properly aligned.
-
Test the Heater:
- Once the new overheat switch is installed, turn the gas supply and power back on. Test the system to ensure that it is operating normally and that the automatic overheat protection is functioning. You may want to run the heater for a short time to verify that the overheat switch correctly shuts the system down if it exceeds the temperature threshold.
Troubleshooting:
-
Frequent Overheating:
- If the overheat switch frequently trips, this could indicate an issue with the heater’s ventilation, heat exchanger, or filter. Make sure that there is no blockage or obstruction preventing proper airflow.
-
Heater Won’t Start After Overheat:
- If the overheat switch has been triggered and the system is not restarting, check the internal temperature of the heater. Ensure that it has cooled down sufficiently and that no other issues are preventing it from operating.
-
Error Codes or Heater Malfunctions:
- If you continue to experience problems after replacing the overheat switch, consult the Braemar user manual for troubleshooting tips or consider having a professional technician inspect the system for further issues.
Conclusion:
The Braemar Wall Furnace Heater Automatic Over Heat Switch (130°C), Part Number 628646, is a vital safety component in Braemar wall furnace heaters. It prevents overheating by automatically shutting off the heater when it exceeds a critical temperature, ensuring safe and reliable operation. Installing a new switch if the old one is faulty is relatively easy and can help restore the proper functioning of the heater.
