Mosaic Patio Heater Won't Stay Lit: Essential Troubleshooting Steps

Mosaic patio heaters are renowned for extending outdoor comfort during chilly evenings. However, if your heater unexpectedly stops staying lit, it can be frustrating. Here are some essential troubleshooting steps to help you resolve the issue:

1. Inspect the Propane Tank

Begin by checking the propane tank. Ensure it is securely connected to the heater and that the valve is fully open. If the tank is empty or has low gas, replace or refill it accordingly.

2. Clean the Burner Assembly

A dirty or clogged burner assembly can prevent proper ignition. Turn off the propane supply and allow the heater to cool. Remove the burner assembly and gently clean it using a soft brush or compressed air. Reassemble the burner and ensure all connections are secure.

3. Examine the Ignition System

The ignition system consists of a pilot light, igniter, and thermocouple. Check if the pilot light is lit. If not, try relighting it according to the manufacturer's instructions. Alternatively, verify that the igniter is sparking. If there is no spark, inspect the wiring connections and replace the igniter if necessary.

4. Check the Thermocouple

The thermocouple is responsible for sensing heat from the pilot light and sending a signal to open the gas valve. If the thermocouple is defective, the valve will not open, and the heater will not stay lit. To test the thermocouple, disconnect the wire from the gas valve and hold it in the flame of the pilot light. If the thermocouple is working properly, you should hear a clicking sound within 30 seconds, indicating that the gas valve has opened.

5. Inspect the Control Valves

Malfunctioning control valves can also prevent the heater from igniting or staying lit. Turn off the gas supply and locate the control valves. Check for any leaks or blockages. If necessary, clean or replace the control valves.

Additional Tips

If you have followed the above steps and your Mosaic patio heater still won't stay lit, there may be a more complex issue. Consider the following additional tips:

Check the owner's manual for specific troubleshooting instructions.
Look for any loose or damaged wires or connections.
Ensure the heater is placed in a well-ventilated area, away from flammable materials.
If the problem persists, contact a qualified professional for assistance.
