How to Troubleshoot Common Issues with Flexible Heaters?
1. Heater Not Warming Up
Check Power Supply: Ensure correct voltage and current are being supplied.
Inspect Connections: Look for loose or damaged wiring, connectors, or terminals.
Test Resistance: Use a multimeter to measure resistance across the heater terminals. Compare with manufacturer specifications.
Control System Check: Verify that the thermostat, temperature controller, or sensor is functioning correctly.
2. Uneven Heating
Installation Issue: Make sure the heater is properly bonded to the surface with no air gaps or wrinkles.
Surface Compatibility: Ensure the mounting surface is clean, flat, and thermally conductive.
Overstretching: For flexible heaters, overstretching during installation can cause uneven heat distribution.
3. Overheating or Burnout
Check Temperature Control: Malfunctioning thermostats or sensors can cause overheating. Replace if necessary.
No Thermal Cutoff: Make sure a thermal fuse or cutoff is included to prevent runaway temperatures.
Surface Insulation: Ensure appropriate thermal insulation is used to avoid heat buildup.
4. Physical Damage
Inspect Visually: Look for cracks, cuts, or burn marks on the heater surface.
Avoid Sharp Bends: Repeated bending or sharp folds can damage internal heating elements.
Chemical Exposure: Check for corrosion or degradation due to exposure to harsh chemicals or moisture.
5. Controller Malfunction
Reset the Controller: Try a power reset or factory reset, if supported.
Replace Batteries (if applicable): Low battery in some controllers can cause erratic behavior.
Update Firmware: For smart controllers, check for software or firmware updates.
