High Quality 780-502 / DS845 Series Replacement 24V Direct Spark Ignition Control Module. 780-502 & DS845 Series. The 780-502 direct spark ignition control is designed as a direct replacement for Robertshaw 780 series intermittent pilot and direct ignition systems. It works with both standard and advanced flame sensing setups. When the thermostat calls for heat, the module provides a high-voltage spark to light the pilot or main burner. If a flame is not sensed within the allowed trial period, the module enters safety lockout to prevent unburned gas from accumulating. This specific module is a non-pre-purge unit, meaning it sparks immediately upon a call for heat without a delay blower cycle. It is universally applicable across a broad range of low-voltage (24 VAC) residential and light commercial gas systems, including gas-fired heating systems, commercial cooking equipment, water heating systems, and gas fireplaces. Built with durable housing for long-lasting performance, it is tested for durability with a high anti-interference margin and wide environmental tolerance. Includes: 1x Ignition Control Module, 2x Mounting Screws, and Double-Sided 3M Tape. (You will receive the exact part shown in the photos). ? PRO INSTALLATION TIP: Verify Your Voltage & Purge Settings! Ensure your system uses a 24 VAC power supply. This module is NOT compatible with line-voltage (120V) or millivolt systems. Additionally, do not use it in systems that explicitly require a pre-purge timing window for safety, as this board is designed for immediate spark. Diagnostic LED: An integrated LED indicator helps technicians quickly identify flame sense, spark, and system status. Versatile Flame Sensing: Supports both local (single-rod combination spark/sense) and remote (dual-rod separate spark and sense) configurations. Lockout Recovery: Features automatic lockout recovery to seamlessly manage safety sequences. Direct Plug-In: Plugs straight in with no wiring changes needed, saving time and cost on the job. Direct cross-reference replacement for the following OEM modules. Nationwide (OE Grade Direct Replacement). 24 VAC, 50/60 Hz. 250 AMP + Valve at 24 VAC. 1.5 AMP at.

This genuine Lennox furnace ignition control module (ICM) part# 97H04. Is brand new, factory packaged, and comes from a smoke/pet free home. These items listed are from an HVAC company that closed a few years ago. We are listing these items by the part numbers on the boxes, please see pictures to verify the items are boxed correctly and also check with a Lennox representative or HVAC certified technician that this part will fit your unit before purchasing! The Ignition Control Module (ICM) is a part of your furnace with one primary function: to light the burners. It receives a signal from the thermostat to start. It sparks (direct spark ignition) and sends power to the gas valve. It shuts down if the Ignition Control Module sensor doesn’t recognize a flame within a few seconds. Unlike a fan board or full control circuit board, an ignition control module does not control the blower. It only controls lighting the burners. Because it uses an electronically-controlled ignition to light the burners, it is more energy efficient, generally safer, and more reliable than the standing pilot light found in most older gas furnace models. However, ignition control modules can still encounter problems. Electronic ignition failure is quite common and can prevent your furnace from turning on. Making the air cooler, warmer, dryer, cleaner and better, with innovative systems that are exceptionally quiet and energy efficient, Lennox makes people feel comfortable in their homes. Since Lennox was founded over 125 years ago, they’ve operated under three guiding principles: Integrity, Respect, and Excellence. Through the unwavering commitment to the customers, they’ve weathered wars, natural disasters, economic recessions, and, most recently, a pandemic. And as excited as Lennox is to see where the future will take them, Lennox is equally grateful to honor the past that has shaped them. Based in Richardson, Texas, near Dallas, Lennox has manufacturing and distribution facilities across North America. Products are available through a network of more than 6,000 independent Lennox Dealers. 78RGF3-50-1, 78RGF3-50-2, 78RGF5-125-1, 78RGF5-125-2, 78UGF3-50-2, 78UGF3-75-1, 78UGF3X-50-1, 78UGF3X-50-2,

Robertshaw 780-845 Ignition Module Intermittent Pilot 24V SP845. Series Application: 780-845, 24V Intermittent Pilot Ignition. Spark Rate: 4 to 15 per Second. Maximum Total Current Load: 1.5 Amps. Flame Failure Re-Ignition Time: 2 Seconds. Safety Lockout Timing: 90 Seconds. Weight : 1.25 LBR Model : SP845 UPC-EAN : 662013644727. The Robertshaw 780 Series Pilot Controls feature flame rectification with solid-state logic and flame sensing to provide automatic sequencing that will ensure proper operation of an intermittent pilot ignition device. When the thermostat calls for heat, the 780 series control simultaneously initiates ignition sparking and opens the pilot valve portion of the gas valve. Pilot flame recognition stops ignition sparking and opens the main valve portion of the gas valve. Pilot burner flame is continuously monitored at a synchronous frequency for the duration of the heating cycle. Should the pilot flame fail during the heating cycle, the control will shut off the main valve until the pilot flame is established. The Robertshaw 780-845 lockout ignition control provides 90 seconds of spark, followed by a six minute time delay (purge) between ignition attempts. If the pilot flame is not sensed after three tries, the control goes into a one-hour lockout period. At the end of the lockout period, if the demand for heat is still present, the unit will repeat the three tries for ignition. Easy-to-install with complete in-depth installation instructions. Pilot and main valves draw 1 Amp at 0.5 power factor. Combined load at 1.5 Amps at 0.4 power factor. 95% relative humidity noncondensing at 104F.
