Every common Senville fault code with what it means, the likely cause, and how CANRO Heating & Cooling fixes it — servicing Senville ductless mini-splits and cold-climate heat pumps across Greater Vancouver since 1999. Licensed Technical Safety BC contractor (gas LGA0043870 · boiler LBP0046450).
Senville mini-splits (LETO / AURA) show E / F / P codes on the indoor display or via a blink count. They run on the widely-used Midea/Tosot platform, so these codes are well documented.
Important: One power-cycle reset is generally safe for a transient fault. If the same code returns within minutes, stop resetting — lockouts exist to protect the heat exchanger, ignition system and gas-valve safety circuit. Note the exact code and call CANRO at (604) 359-1081. We carry common Senville parts on every truck, so most code-triggered faults are fixed in one visit. Smell gas? Leave and call the gas utility emergency line first.

This Senville error-code guide is maintained by the CANRO Heating & Cooling team from 25+ years of HVAC install, service and repair across Greater Vancouver. Flash-count and code behaviour described match current Senville model manuals; exact codes can vary by model and series, so confirm against your unit’s manual or tell us the code when you call. Last reviewed June 2026.
Each Senville code points to a specific fault — ignition, pressure/draft, high-limit, flame-sensing, blower or communication. The guide above lists each one with its cause and fix. Tell us the exact code when you call (604) 359-1081 and we usually know the likely cause before arriving.
One power-cycle reset is fine for a one-off fault. If the same code returns within minutes, stop — repeated resets stress the ignition, gas-valve and heat-exchanger safety circuits. Note the code and call.
