About this item

Product Details

Put refrigerated products in sight and within reach.

The True GDM-23 keeps bottled beverages and packaged foods visible and within easy reach in cafés, convenience stores, cafeterias, markets, and self-service areas. Its glass-door format combines adjustable merchandising space with bright interior lighting, while the bottom-mounted condensing unit raises the lowest shelf to improve product visibility. Eligible purchases from IceMachinesPlus are covered by the 30-Day Price Match Guarantee, adding some reassurance when you order.

Before ordering, confirm that the True GDM-23 matches the products, placement, and electrical service at your site. This model is a medium-temperature refrigerator, not a freezer. True rates the cabinet to maintain 33°F to 38°F, and its model-specific NSF/ANSI Standard 7 listing covers the storage or display of packaged or bottled products.

The checks below connect the cabinet specifications to the decisions that matter before delivery. Compare them with the current True GDM-23 manufacturer specifications before ordering, then verify the delivered cabinet against its data plate before installation.

Purchasing and installation details to confirm for the True GDM-23
Planning check What to know
Configuration This listing is for model GDM-23-HC~TSL01_WH, the white-exterior configuration. Confirm that the complete suffix appears on the order.
Approved use Refrigerated storage or display of packaged or bottled products. This isn’t a freezer.
Holding range True rates the cabinet to maintain 33°F to 38°F under its specified operating conditions. Verify actual product temperature after loading.
Installed size Allow for a 27-inch width, 29⅞-inch cabinet depth, and 78⅝-inch height. The handle adds approximately 1⅝ inches to the stated depth.
Electrical service Provide a grounded, dedicated 115V/60/1-phase, 15-amp outlet for the included NEMA 5-15P plug. The rated draw is 5.4 amps. Don’t use an adapter or extension cord.
Placement Install indoors with ventilation openings clear, the door able to swing fully, and practical access to the bottom-mounted condenser. Follow the current manual for final clearances.
Startup If the cabinet was laid on its back or side for four hours or less, leave it upright for twice that duration before connecting power. If it was laid down for more than four hours, leave it upright for 24 hours. After connecting power, run it empty for 24 hours before loading products.

ENERGY STAR lists the True GDM-23 base model as a certified vertical transparent-door refrigerator with reported daily energy consumption of 1.95 kWh under standardized testing. Actual energy use will vary with ambient conditions, product loading, door openings, and maintenance.

Once the site is ready, arrange the True GDM-23 around the packages customers and employees need to reach. The four shelves adjust in ½-inch increments, so use the space deliberately instead of simply filling every available gap.

  • Seat all four corners of each shelf securely in their clips, with the shelf support bars facing down.
  • Keep products from pressing against the cabinet sides or back.
  • Maintain at least 4 inches between products and the evaporator housing so refrigerated air can circulate.
  • Keep the lower grille and the cabinet’s ventilation path unobstructed.
  • Check that the self-closing door returns to a complete seal after stocking.
  • Measure product temperature directly. The control or display can reflect cabinet-air and refrigeration-cycle changes rather than the temperature at the center of a package.

Loading discipline matters because a packed display can still cool unevenly if cartons or bottles block the internal airflow. Give the True GDM-23 time to recover after the door has been open for stocking, and investigate persistent warm product temperatures instead of lowering the control repeatedly. Excessive control adjustments can create service problems without correcting blocked airflow, a dirty condenser, or a poor door seal.

The bottom-mounted refrigeration system keeps the condenser accessible behind the lower grille, but that access has to remain usable. True’s current GDM manual recommends checking the front and back of the condenser coil monthly and clearing dust and debris when present. Disconnect power first, use only the methods permitted in the True GDM installation manual, and don’t place filter material in front of the coil. If the coil can’t be cleaned safely or completely, use a qualified refrigeration service provider.

Clean the removable magnetic door gasket and interior routinely, but don’t wash the True GDM-23 with a hose or pressure washer. Check that the cabinet remains level because leveling affects condensate removal and door operation.

The True GDM-23 uses R290 hydrocarbon refrigerant. Keep ventilation openings unobstructed, don’t puncture refrigerant tubing, and leave sealed-system diagnosis or repair to trained service personnel.

If this footprint, temperature range, or merchandising format doesn’t match the application, compare other True one-section glass-door merchandising refrigerators or browse the wider range of refrigerated merchandisers. Match the complete model suffix, finish, door configuration, voltage, dimensions, and operating requirements before ordering.

A few details about this refrigerated merchandiser are worth confirming before purchase.

Is the True GDM-23 a refrigerator or a freezer?
The True GDM-23 is a medium-temperature refrigerator, not a freezer. True rates it to maintain cabinet temperatures from 33°F to 38°F under specified conditions.
What products can be stored in the True GDM-23?
Store packaged or bottled products in the True GDM-23. Its model-specific NSF/ANSI Standard 7 listing covers those applications. For an open-food application, confirm suitability with True and the local authority instead of assuming that the packaged-product listing covers it.
What temperature does the True GDM-23 maintain?
The True GDM-23 maintains a rated cabinet range of 33°F to 38°F. Check actual product temperature because the control or display may show cabinet-air or refrigeration-cycle changes rather than product temperature.
How often should the True GDM-23 condenser be cleaned?
Inspect the front and back of the condenser coil monthly, and clear dust or debris when present. Grease, lint, and other airborne debris may require more frequent checks. Follow True’s approved procedure, and use a qualified technician if the work extends beyond routine maintenance.
Why isn’t my True GDM-23 cooling properly?
First check power, door closure, internal airflow, ventilation openings, product loading, the temperature-control setting, and condenser cleanliness. Keep the door closed long enough for the cabinet to recover after stocking. If cooling remains inadequate, or the compressor runs without the cabinet recovering, contact a qualified refrigeration technician; the R290 sealed system isn’t a do-it-yourself repair.
