The Toyotomi Transformer L60AT/L60AT-W, part number 20479917, is a replacement low-voltage electrical transformer used in select Toyotomi Toyostove heaters to provide the proper control voltage for ignition controls, gas valves, and other safety circuit components. It converts incoming line voltage to the lower control voltage required by the heater’s control system, helping ensure reliable operation of ignition modules, flame sensors, and safety interlocks. This transformer is manufactured to match the original equipment specifications so it fits directly into place when replacing a worn, noisy, or failed transformer in the heater’s electrical assembly.
This transformer can be used in place of part number 20478317 where specified, making it interchangeable for compatible Toyotomi models that require the same control voltage and mounting configuration. It is intended for use during service or repair when the original transformer shows signs of electrical failure such as no ignition spark, intermittent control power, buzzing noise, or failure to energize the control circuits. Installation must follow the heater’s model-specific service instructions to ensure correct wiring, secure connections, and proper mounting to avoid operational faults.
What’s Included: One (1) Toyotomi low-voltage replacement transformer for L60AT and compatible models.
Installation Limits: For use only on compatible Toyotomi Toyostove heaters; install with the heater powered off and ensure all wiring connections are secured and insulated per the service manual.
Compatibility: Compatible with Toyotomi Toyostove L60AT, L60AT-W, and other models that utilize the same control transformer configuration; can be used in place of part number 20478317 when the specifications match.
Laser 60AT, Transformer is located next to Drip Tray.
