The Rheem-Ruud AS39758 Ignitor Assembly is a high-precision OEM replacement part engineered for reliable ignition in commercial and residential gas-fired HVAC systems

Using a 240V actuator on a lower voltage system will prevent the motor from engaging

its robust shutoff capabilities and 15 psi steam rating make it ideal for both one-pipe and two-pipe configurations where an angle valve is required at the radiator inlet

intermittent "no heat" errors

Fenwal 01-017023-000 Thermoswitch 30067439-890 The Rheem-Ruud AS39758 Ignitor AssemblyThe Fenwal 01 017023 000 Thermoswitch is a high precision cartridge type temperature control engineered for demanding industrial HVACR applications. Operating on the differential expansion principle, this strut and tube thermostat utilizes a 300 series stainless steel shell as the active sensing element, ensuring a nearly instantaneous response to thermal shifts. Designed for a broad temperature control range of 100F to 600F, this unit is configured
