Triangle Tube fault codes can vary by model and series. Use this as a guide — the same code can have more than one cause. Our Technical Safety BC–licensed technicians read the code, confirm it against your unit's manual, and diagnose the true cause before any repair.
Likely causes of Triangle Tube error E5
- Failing or obstructed combustion blower
- Loose or damaged blower wiring/connector
- Blocked intake or exhaust venting

- Debris in the fan housing
What you can safely check
- Check the outdoor intake and exhaust vent terminals are clear
- Note the code and contact a licensed technician; do not open the unit
Beyond these checks, do not open the unit or touch gas/electrical parts — BC law requires a licensed gas fitter. Call us for a proper diagnosis.
