Genie Stealth 500 Belt Drive Garage Door Opener, Model 2055-LO

Attached garages wanting a quiet belt drive without smart features

A steel-reinforced belt drive opener that the listing sells as the Stealth 500 and Genie documents as Model 2055, the QuietLift 550. It ships with a single-button pre-programmed remote, a lighted push button and two Genie LED bulbs, and it fits sectional doors up to 7 feet and 500 pounds.

Fit and limits

Strengths

  • Genie's warranty table gives the belt fifteen years and the motor ten
  • HomeLink and Car2U work out of the box with no repeater box or bridge
  • Remotes arrive pre-programmed and two Genie LED bulbs are in the box

Caveats

  • Core parts and accessories carry only one year in Genie's own table
  • Neither source lists Wi-Fi or a backup; Genie prints a California SB-969 notice
  • An 8 foot door needs an extension kit that Genie sells separately

Two names, one model number, and a short kit list

The listing's title calls this the Stealth 500 and gives the model as 2055-LO, with manufacturer part number 38958RT and UPC 050049021979 in its details block. Genie's own page for the same model number heads it QuietLift 550 instead, so you will see both names attached to model 2055.

The listing's included components field names two Genie LED garage door opener bulbs and a single-button pre-programmed remote, and its bullets add a lighted push button and the Safe-T-Beam system. No keypad and no wireless wall console appear anywhere in that list.

Genie's Model 2055 page publishes no components list of its own, so everything known about what ships in this box comes from the listing. If the exact accessory set matters to you, confirm it with the seller before you order rather than assuming a fuller kit.

The motor figure is written two different ways

The listing describes a 1/2 HPc DC motor paired with a steel-reinforced belt drive. Genie's Model 2055 page prints the motor as a half to three-quarter HPc unit, so the maker's own range is wider than the single figure the listing settles on. Ask Genie which applies to the unit you are sent.

Genie defines the unit itself in a footnote on that page: horsepower comparable, or HPc, designates that the opener meets Genie's lifting force specification for the amount of horsepower mentioned. Read it as Genie's own comparison figure rather than as a measured motor horsepower rating.

Both sources agree about the door. Genie's page says the motor can operate residential sectional garage doors up to 7 feet in height and 500 pounds in weight, and a footnote on the same page says an extension kit is required for 8 foot high doors.

What the manual rules out, and what this kit does not include

The manual Genie links from the Model 2055 page carries a warning panel on its cover restricting the opener to a sectional residential door. The same page tells you not to use photocells from other manufacturers or from other openers with this opener, and page 18 repeats that only the supplied Safe-T-Beam sensors may be fitted.

Neither the listing nor Genie's Model 2055 page lists Wi-Fi, an app or a battery backup as part of this kit. Genie's page does carry a notice that California state law SB-969 requires all installed garage door openers in that state to have battery backup as of 1 July 2019.

The warranty document Genie links from the same page heads its battery backup column with the words if equipped, so a backup is not assumed to be fitted to every model in that table. If you are buying for a California address, settle that question with Genie or the seller first.

Genie's warranty table says more than the listing field

The listing's manufacturer warranty description gives four lines: one year accessories, one year parts, a fifteen year belt warranty and a limited ten year motor warranty. Genie's own warranty document splits the same cover across six columns in a model-by-model table, and the two agree.

The row that covers 2055 and 2053 reads ten years on the motor and gearbox, one year on core parts, one year on accessories and other parts, fifteen years on the belt, and one year on the battery backup if the opener is equipped with one.

Genie defines the core unit as the powerhead, the wired or wireless wall control, the Safe-T-Beam system, the J-arm and the rail, and those parts sit in the one year column here. The document also excludes labour charges, is not transferable, applies only to residential installations in the United States and Canada, and does not cover batteries, use of an extension cord, or missing parts from clearance and open box sales.

The monthly list the manual hands you

Genie's maintenance schedule is a table rather than a suggestion. Monthly items are the contact reverse test, lubricating the rollers and hinges with a light weight general purpose grease, a Safe-T-Beam system check for loose connections and dirty lenses, a door balance check and a battery backup test where one is fitted.

The belt is inspected yearly for excessive slack, while remote batteries and light bulbs are changed as needed. The remote takes a CR2032 coin cell, and the manual calls for A19 bulbs rated at 60 watts maximum in incandescent, CFL or LED equivalent, warning that standard LED bulbs may reduce remote range.

Where the manual draws a hard line is the door itself. It warns that springs, cables, brackets and pulleys are under extreme pressure and tension, tells you not to repair or adjust them, and sends the door inspection it describes to a trained door system technician rather than to the owner.

Wall control, sensors and getting help with the install

The manual sets physical rules for the controls. The wall console must sit within sight of the door, far enough from it that you cannot touch the door while using the console, and at least 5 feet above the floor. It also warns that other wall controls can cause unexpected door operation.

On the sensors the manual is absolute. Only the Safe-T-Beam sensors included with the opener may be used, and it says not to fit photocells from another manufacturer or from another opener. It also sets the mounting height at 5 to 6 inches above the floor; the alignment rules that go with that are in the manual and are not reproduced here.

For the physical assembly and installation the manual points you elsewhere rather than walking you through it here: it tells you to contact your local Genie dealer or Genie's own number for professional assistance. Treat the poster and manual as the only step-by-step source, and leave door hardware to a technician.
