How to Fix / Troubleshooting
Danger: If you smell gas strongly, shut off gas at the main shutoff valve immediately, turn off power, and ventilate the area. Do not light flames or operate electrical switches nearby.
- Do not attempt DIY gas repairs: Gas leaks and combustion issues must be handled by a licensed gas technician.
- Visual inspection only: You may visually check for obviously loose unions or damaged flexible connectors, but do not tighten or disassemble gas piping unless qualified.
- Professional leak test: A technician will perform a leak-down test and use approved leak-detection solution on all joints, then repair or replace faulty components.
