Rancilio 140° Steam Temperature Thermostat OEM stock replacement steam thermostat for Rancilio machines, rated at 140°C, and includes the mounting bracket. COMPATIBILITY Fits: Rancilio machines using the OEM 140° steam thermostat Replaces: Rancilio part # 34200295 INSTALLATION A job for someone comfortable with basic electrical work; the mounting bracket is included. PRO TIPS Use thermal paste on the sensing head before bolting or clamping the thermostat down, it fills microscopic gaps between the switch and contact surface for accurate heat transfer, and it's especially important on pipe-mount installs. Don't use it as an adhesive. Choose a thermally-stable synthetic paste that won't harden, dry out or melt in normal use, a degraded thermal interface is a common reason a freshly-replaced thermostat still cycles steam temperature inconsistently.
