True freezers
Freezers built like the walk-in they descend from.
True freezer columns and undercounter freezers carry the commercial DNA of the brand: stainless interiors, forced-air cooling and plain-language alarm statuses. The freezer alarm threshold is honest - one hour above 32°F and the control tells you.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Columns
Freezer columns
24, 30 and 36-inch built-in freezer columns matching the refrigerator columns.
Undercounter
TUF-24
24-inch undercounter freezer, solid or overlay panel door.
Drawers
TUF-24D
24-inch freezer drawers for island installs.
Combined
TR-SBS freezer side
The freezer circuit of the 42/48-inch side-by-sides - its own compressor and evaporator.
Start with the symptom
Common True freezer problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Freezer
Freezer not holding zero
Condenser airflow and defrost first - the honest order before sealed-system work.
Frost
Frost building on the back wall
Defrost heater, probe or drain - the pattern tells which.
Symptom
Drawer unit stopped sealing
Freezer drawers carry weight; slides and gaskets are real service items.
Sound
Runs loud
Forced-air fans and condenser condition - commercial-style and fully serviceable.
Ice & water
Ice crystals on food
Temperature cycling or door seal - diagnosed from the alarm history.
Power
After a power outage
Alarms latch to tell the story - photograph before clearing.
Series and model numbers
True freezer series we service
The full model string from the gray serial tag - hinge, finish and revision letter included - decides the parts book.
Undercounter
TUF models
Model numbers
TUF-24-R-SS-C, TUF-24D
What to note
R/L hinge, SS or OP (overlay panel); the trailing revision letter matters for parts.

What to note
Hydrocarbon refrigerant work follows its own safety procedure.
Model label
Where to find your True model number
The gray serial tag sits on the interior wall, top left; True's official serial-tag locator PDF maps every model. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
True freezer alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
High Temperature alarm
What it means
One hour above 32°F in the freezer - food-safety relevant.
Safe check
Keep the door closed, note the alarm duration and book same-day; inventory-risk calls get priority.
True diagnostics
True freezer error codes, decoded.
True freezers report plain-language statuses, not numeric codes - per True's official service manual. Commercial-line P1/E1 tables online do not apply to residential units.
Status message · Refrigeration Error
Setpoint not reached in 15 hours
What it commonly means
The freezer ran 15 hours without pulling down - compressor, airflow or charge.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Sealed-system and condenser diagnosis before any component is condemned.
Status message · Evaporator / Compartment Probe Failure
Sensor failures
What it commonly means
A failed probe degrades defrost timing or temperature control; with both out the unit self-protects on a 3-minute cycle.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Probes are tested and replaced; defrost and pull-down verified after repair.
Status message · Door Ajar
Door open 7 minutes
What it commonly means
The alarm that most often is not a fault - but recurring with a closed door means switch or alignment.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Gasket, hinge and switch service.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
True products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.

Preventive service and owner care
True freezer maintenance
Alpha Pro provides preventive and general maintenance for True freezers. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Door seal: keep the gasket clean; confirm the door closes and seals without force.
Frost watch: note any frost pattern early - photographs help diagnosis.
Airflow: keep interior vents unblocked and clearance around the unit.
Defrost drain: keep accessible drain areas clear per the manual.
Professional maintenance
Inspection follows the appliance design
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Temperature performance and recovery
Compressor and condenser condition
Evaporator and frost condition
Defrost system operation
Door gasket and alignment
Drainage and condensation
Control response and displayed faults
Installation and ventilation
Diagnosis before parts
A straightforward three-step service process
1
Describe the symptom
Call or book with the model label, exact behavior, any displayed codes, photos, and access notes.
2
Evaluate the system
The technician examines the reported condition in context: temperatures, frost pattern, airflow, defrost behavior, controls, and relevant components.
3
Review the recommendation
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.
Service areas and operating context
True freezers across San Diego
Alpha Pro serves True freezers in communities including La Jolla, Del Mar, Rancho Santa Fe, Carmel Valley, Poway, and the full San Diego County footprint below — ZIP by ZIP. Installation and room conditions vary from the coast to inland homes.
Coastal homes
Moisture, ventilation, and accessible surfaces
Recurring condensation, marine exposure, ventilation limits, and visible corrosion can be useful details during repair or maintenance.
Inland homes
Ambient heat and equipment environment
Share room conditions, recent heat events, ventilation restrictions, and when the symptom appears.
During maintenance, accessible metal surfaces can be inspected for corrosion, moisture exposure, or conditions that may warrant attention. Location alone does not establish the cause of a failure.
There is no honest universal age or price threshold. Start with the exact model and a diagnosis.

Helpful answers
True freezer service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day True freezer repair in San Diego?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a True freezer?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
What does the High Temperature alarm mean on a True freezer?
The cabinet spent an hour above 32°F. Keep the door closed and book promptly - the alarm exists to protect inventory, and the visit finds why it tripped.
Does a True freezer show error codes?
It shows plain-language statuses - Refrigeration Error, probe failures, Door Ajar - rather than numbers. That is by design and verified against True's service manual.
Where is the serial number?
On the gray tag on the interior wall, top left. Photograph the whole tag - hinge and revision letters route the parts.
Is R600a refrigerant a problem for repair?
No - it just requires the proper hydrocarbon procedure, which is part of the service standard for these units.
Can you service True freezer drawers?
Yes - slides, gaskets and the cooling system are all diagnosable; drawer units get the same per-circuit approach.
