Robertshaw 790-400 RAM-4 Intermittent Pilot Ignition Control 120V

The Robertshaw 790-400 RAM-4 is an intermittent pilot ignition control module designed for gas heating equipment operating at 120 volts. This control initiates ignition sparking and opens the pilot valve simultaneously when the thermostat calls for heat, ensuring reliable ignition in furnaces, boilers, and other gas-fired heating appliances.

Key Features:

• 120V intermittent pilot ignition control with 6-pin connections
• Continuous flame monitoring for enhanced safety and reliability
• Automatic shutdown of main valve if pilot flame extinguishes
• Continuous retry for ignition with non pre-purge operation
• High-capacity 5.0 amp gas valve relay for durable performance
• Advanced flame sensor technology requiring minimal current (0.7mA)

This control module serves as a direct replacement for several OEM part numbers including Imperial 37061 and 37110, Tri-Star 390232, and AllPoints 44-1743. The RAM-4 design ensures optimal safety by continuously monitoring the pilot flame and halting the main valve until the pilot is re-established if the flame goes out, making it an essential component for maintaining heating system efficiency and safety.
