    Damper Motor Repair

    Monday, June 24, 2013

    Looks like whoever designed this damper did so with deliberate failure (and replacement) in mind. More money for the company, the distributors and the repair folks. Sound familiar? After several years of use, the nylon gear will strip. It can be repaired (one time) by carefully taking the motor apart and 'flipping' the gear to the 180 degree setting. Some tabs have to be bent and then re-bent, but the job should take about 30 minutes and give you another 'n' years of life. What would be really nice if these jokers would sell just the nylon gear. Shame on them!

    when it works, it works.

    more reliable nylon gear.

    Great resource

    Saturday, January 19, 2013

    I was told by my local plumbing store that I would have to order the entire damper unit. I was thrilled that you had the linkage & motor in stock! The part was delivered on schedule to my doorstep! I will be sure to look to drillspot first in the future THANKS

    Easy to install & was back in service in 5 minutes.

    Great service and price.

    Thursday, January 17, 2013

    I recently bought a "Cadillac" service plan for my FHA system. Naturally, dampers weren't covered .... . Oh well, got a quote, $349. Took the number off the unit, went to this site, had the part in a few days. Installed the new part in maybe 60 seconds, saved almost $300. Thank you very much.

    Ease of install.

    Quick deliver. Item as advertised!

    Tuesday, November 20, 2012

    Worked as advertised.. I'm no handy man and this took me 5 minutes to install.. Saved me 300 dollars by doing it myself.. U just need an Alan or "hex" wrench to unscrew the black bar on the mounted unit.. After that the installation process takes minutes!

    Easy to install and delivered quickly

    So far so good works as promised and its been a week!

    Quick, Easy, and Saved Lots of Money

    Tuesday, June 05, 2012

    Read reviews online and most of them were positive and stated that it was a fairly simple fix. Took a chance and bought two, because both damper motors were bad. It took me about 45 minutes, but should have only been about 30 min because I ran into a broken wire that I had to repair. I hope these new updated motors last longer then the first ones. An A/C company quoted me $1200.00 to replace the entire unit including the damper housing. What a rip off that would have been! All that needed to be replaced was the damper motors. Online it cost me $135.00 delivered. Go ahead and take the chance to fix it yourself. Do it in spring or fall when the attic is cooler.

    Easy Fix to Furnace Duct System

    Tuesday, March 13, 2012

    Easy to install. Drillspot is great - fast delivery, good website, decent pricing.

    Simple to swap in new unit

    Two prior ones (initial install and one replacement) failed. Get a clicking noise - the plastic gear evidently strips after a few years of usage. This is a replacement SKU for the first two, so maybe it will last longer.

    This is a replacement damper an earlier Honeywell M847D damper for a Honeywell zone heating system. The old one had stripped gears and made a clicking noise while not operating fully. This is a direct replacement and was easy to install. It's only been in service a month, but appears to work fine. I ordered from Drillspot as the feedback seemed mostly positive. The package arrived in less time than quoted.

    The damper motor was the perfect replacement part for the broken motor that I needed to replace.
