These motors are also replacements for the Hansen 135-6 motor, as well as other brands with the same footprint. - Durable and Reliable: Our all metal gears and precision engineering get rid of the failure prone thin metal or plastic OEM gears from Honeywell. Our gears are twice as wide as the new “improved” Honeywell plastic-covered motors. - Includes Everything You Need for Easy Installation: Don't be left in the dark when your new motor, damper, transformer, or thermostat fail to work. Our handy 24 volt test light and troubleshooting guide, included with motor, allow you to test power to your motor and perform a complete diagnostic evaluation of your zoning system when used with our 2 page troubleshooting guide. - Voltage: 24 VAC +/- 10%, 60 Hz, 0.36A - Torque Rating: Power open 32 in. oz./spring close 32 in. oz. - torque is consistently delivered throughout the full 90º rotational operating range to open and close the damper, irrespective of whether the actuator is operating in Power Advance Mode (energized) or Spring Return Mode (de-energized). - Speed Stroke and Rotating Angle: Motor driven 30 sec./spring return 6 sec. and 93.5º - Reliability: Quality tested for over 120,000 cycles for exceptional operation with no decay in delivery torque over the life of the actuator - Noise Level: Very quiet operation, typically ≦ 40dB at 3’ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NBEO02L | | Best Sellers Rank | #62,810 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,755 in HVAC | | Brand | Retrozone | | Brand Name | Retrozone | | Customer Reviews | 4.6 out of 5 stars 454 Reviews | | Horsepower | 6 watts | | Included Components | Damper motor | | Item Dimensions W x H | 3.25"W x 3.63"H | | Manufacturer | ARD ZD | | Material | Copper | | Material Type | Copper | | Model | RZ3-1M | | Model Name | gear | | Number of Items | 1 | | Part Number | RZ3-1M | | Product Dimensions | 3.25"W x 3.63"H | | UPC | 680474058020 | | Unit Count | 1 Count | | Voltage | 24 volts | ## Product Details - **Brand:** Retrozone - **Horsepower:** 6 watts - **Model Name:** gear - **Product Dimensions:** 3.25"W x 3.63"H - **Voltage:** 24 volts ## Images ![Replacement Damper Motor Actuator for Honeywell ARD ZD M847D 2 Wire Spring Motor RZ3-1MNormally Ships Same Day - Image 1](https://m.media-amazon.com/images/I/61ba5ms5s5L.jpg) ## Questions & Answers **Q: what rpm is this Actuator?** A: The short answer is “adequate to respond to the damper shutter demands” and I don’t mean to sound like a smart a__. The motor turns quickly but, because it operates through a gear train, it’s effect is much slower, but with greater torque (leverage). So the answer depends on which end of the process you measure rpm. I would advise against using this unit for an application for which it is not intended. Hope this helps more than angers. Trying to help **Q: Will this work to replace the M847D1012?** A: I replaced two M847D1004 models so can't say about the 1012. **Q: direct replacement for M847D1004 ?** A: Not sure. I replaced by appearance and it worked. May not be the same for you. Return of electronic parts may not be allowed so it is probably not economical to speculate. **Q: Will this replace Hanson Corporations 135-6-20 (645 1543)?** A: Well, those numbers dont mean anything to us, and hansen makes lots of motors, but if you are referring to the complete hansen motor that looks like ours in the pic, but maybe withyellow wires, as used by Jackson Systems and others, then yes it will work. ## Frequently Bought Together - Replacement Damper Motor Actuator for Honeywell ARD ZD M847D 2 Wire Spring Motor RZ3-1MNormally Ships Same Day - Honeywell M847D Zone Valve Actuator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/38943431-replacement-damper-motor-actuator-for-honeywell-ard-zd-m847d-2](https://www.desertcart.sg/products/38943431-replacement-damper-motor-actuator-for-honeywell-ard-zd-m847d-2) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-03*
