To clean a thermocouple on a propane heater:
• Turn off the gas and disconnect the power supply.
• Wipe it down with a soft cloth to remove any dust or debris.
• Use light oil and q-tips to lubricate the connection points.
• Reconnect the power supply and turn on the gas again.
Cleaning your thermocouple regularly will help ensure that your propane heater is working efficiently, safely, and without interruption.
