It would start, sometimes, then stop. Wiggling the wires seemed to help so I decided the springs connector to the lockout/ignition controller LH33WZ512A had worn out. The 6-pin connector on the old controller looked hard to replace so I took a chance and ordered this controller with friendlier looking connectors. I used $7 worth of "disconnect" terminals that came with a crimping tool and it was within my capabilities. Installation notes: I didn't seem to need to hook everything up. 'PV/MV common' and 'Transformer ground' on the new controller were left floating. I connected the sense to the adjacent terminal on the controller as suggested by the instructions. From the old connector to the new controller: Black - ground Blue - Thermostat 24V Yellow - Pilot Valve White - Main Valve Brown - No connection (This floats at 24V when the furnace is on. I think it has something to do with the old flame sensing mechanism but this controller doesn't seem to need it.) I was really pleased how quickly the furnace started up. Just a few seconds; much quicker than the old controller. Also, when I turned off the gas, the controller immediately locked out until I turned the thermostat down and back up again. Seems safe. Not sure how the flame sensing works; seems like magic; but works. At one point I connected the brown wire to PV which is wrong and the controller LED blinked then shut down which was helpful in guessing the connections. I had paid some con artist $90 to quote me $650 to replace the perfectly good control valve. This box fixed my problem for $80. Great product! Review: Easy install and works well - It was easy to install although I had to drill a few holes on the bracket of the furnace. Just keep track of the wires and where they go. ## Features - Ignition module - Intermittent pilot ignition - Electrical connections: 1/4" quick connect - Bracket: universal - For use with residential & commercial heating equipment ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Standard Plumbing Supply | | Item model number | 780-845 | | Product Dimensions | 12.07 x 3.81 x 7.62 cm; 408.23 g | | ASIN | B003U1RA3Q | ## Images ![Robertshaw 780-845 Ignition Module, Intermittent Pilot, 24V - Image 1](https://m.media-amazon.com/images/I/51-3Yeb6aIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic *by S***X on 15 January 2020* I have an old Carrier 58gsc.

Great product! ### ⭐⭐⭐⭐⭐ Easy install and works well *by A***R on 14 November 2024* It was easy to install although I had to drill a few holes on the bracket of the furnace. Just keep track of the wires and where they go. ### ⭐⭐⭐⭐⭐ Great Replacement for SP 745 on a Lennox Whisper Heat *by G***D on 27 October 2021* The Robertshaw ignition module worked great and the replacement from a Lennox SP 745 was straight forward. The wire positions are not all in the same spot so you will need to make note of this as you disconnect the old module. The ignition terminal on the Robertshaw is labeled SPARK, this is the only difference for labelling. The screws that came with kit were a bit too short so I used a more suitable length. My furnace now works great again, I am very happy with the product which saved me a lot of money in the end. ## Frequently Bought Together - Robertshaw 780-845 Ignition Module, Intermittent Pilot, 24V - Heat N Glo Thermocouple For Heat And Glo And Hearth & Home Fire Places - Hearth & Home Technologies Replacement Variable Valve, Natural Gas (750-500) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/379375987-robertshaw-780-845-ignition-module-intermittent-pilot-24v](https://www.desertcart.be/products/379375987-robertshaw-780-845-ignition-module-intermittent-pilot-24v) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-17*
