There are several possible reasons why a pilot light won't stay lit on a gas appliance:

Thermocouple issue: The thermocouple may be faulty or not positioned correctly, which can prevent it from detecting the pilot light and shutting off the gas supply.
Dirty pilot assembly: Dirt, dust, or debris may be blocking the pilot light, causing it to go out frequently.
Gas pressure problem: If the gas pressure is too low or too high, it can affect the ability of the pilot light to stay lit.
Faulty gas valve: The gas valve may be faulty, preventing enough gas from reaching the pilot light to keep it lit.

To resolve this issue, you can try the following steps:

Clean the pilot assembly: Use a small brush or compressed air to remove any dirt or debris that may be blocking the pilot light.
Check the thermocouple: Make sure the thermocouple is properly positioned and not damaged. If necessary, replace the thermocouple with a new one.
Adjust the gas pressure: Contact a professional to adjust the gas pressure to the correct level for your appliance.
Replace the gas valve: If the gas valve is faulty, you may need to replace it with a new one to ensure proper gas flow to the pilot light.
