Digital Bradley smoker shows E5 and will not maintain set temperature.

Safety first: Disconnect power and verify the cabinet is cool before accessing internal wiring. Never bypass a high‑limit or thermal fuse for normal operation.

Steps to troubleshoot E5:

• Locate high‑limit device: On many Bradley electric smokers, a high‑limit thermostat or thermal fuse is mounted on or near the heating element housing or rear wall.
• Inspect wiring: Check that the wires to the high‑limit device are firmly attached and not burnt or broken. Repair any damaged connectors.
• Test continuity: With the smoker unplugged, disconnect one lead from the high‑limit thermostat or thermal fuse and test for continuity with a multimeter. An open reading indicates the device has tripped or failed.
• Replace failed device: If the high‑limit or thermal fuse is open, replace it with the exact Bradley‑specified part. Do not substitute with a higher temperature rating.
• Check for root cause: Investigate why the high‑limit opened: blocked vents, excessive grease buildup, or operating the smoker above rated temperature can cause overheating. Clean vents and interior thoroughly.
• Control board check: If the high‑limit tests good but E5 remains, the control board may be faulty and require replacement.
