True refrigerators
Commercial iron, residential address.
True Residential refrigerators come off the same O'Fallon, Missouri floor as True's commercial coolers: 300-series stainless inside and out, balanced forced-air cooling, and on the big built-ins dual compressors with dual evaporators. The controls speak in plain-language statuses, not cryptic codes.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Flagship
TR-42 / TR-48 side-by-side
42 and 48-inch built-ins with dual compressors and dual evaporators, solid or glass door.

15 and 24-inch undercounter refrigerators, drawers and beverage centers - UL-rated for outdoor use.
Start with the symptom
Common True refrigerator 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.
Cooling
One side warm on a TR-48
Dual compressors run each side independently - one circuit can fail while the other holds perfectly.
Symptom
Runs constantly
Balanced forced-air systems are sensitive to condenser dust and clearance - airflow first, charge later.
Door
Glass door sweating
Ambient humidity versus door heater performance on SG models.
Frost
Stainless interior frosting
Defrost system territory - photograph the pattern before clearing it.
Door
Undercounter unit stopped outdoors
Outdoor-rated units still need a live GFCI and ventilation - checked before any component verdict.
Alerts
Alarm history questions
The control's alarms are the diagnostic record - do not clear them before the visit.
Series and model numbers
True refrigerator series we service
True encodes door style, hinge and revision directly in the model number - the full string from the serial label is what routes parts and service.
Built-in
TR-SBS models
Model numbers
TR-48SBS-SS-B, TR48SBSSGC
What to note
SS solid door, SG glass; the trailing letter is the revision - it decides the parts book.
Columns
TR-REF models
Model numbers
TR-30REF-R-SS-C
What to note
R or L in the number is the hinge side.
Undercounter
TUR / TUR-D / TBC
Model numbers
TUR-15, TUR-24, TUR-24D, TBC-24
What to note
D marks drawer units; all undercounter models run R600a refrigerant.
Model label
Where to find your True model number
The serial label is a gray tag on the interior wall, top left; on TR-42/48 it sits on the left wall near the freezer wire basket or the top refrigerator drawer. True publishes an official serial-tag locator. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
True refrigerator 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
The display raises it after an hour above 50°F in the refrigerator - a real inventory warning.
Safe check
Keep doors closed and note how long the alarm has been up; photograph the display for the technician.
Message / alert
Door Ajar
What it means
Sounds after a door stands open 7 minutes.
Safe check
Check for a drawer or package blocking closure; a recurring alarm with a sealed door is a switch or alignment visit.
True diagnostics
True refrigerator error codes, decoded.
True Residential controls show plain-language statuses on the LCD rather than numeric codes - verified against True's official 15/24-inch service manual. The P1/E1-style codes circulating online belong to True's commercial Dixell controllers and do not apply to residential models; they are deliberately excluded here.
Status message · Refrigeration Error
Setpoint not reached in 15 hours
What it commonly means
The system ran 15 hours without reaching setpoint - compressor, condenser airflow or charge territory.
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
Power-cycle resets the flag; the visit tests the sealed system and condenser before anything is condemned.
Status message · Compartment Probe Failure
Cabinet sensor failed
What it commonly means
The compartment temperature probe reads open or shorted - the unit estimates temperature meanwhile.
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
The probe is tested and replaced; on current software the reset is a power-cycle after repair.
Status message · Evaporator Probe Failure
Defrost sensor failed
What it commonly means
The evaporator probe failed - defrost timing degrades first.
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
Probe replacement and defrost verification.
Status message · Both Probe Failure
Both sensors down
What it commonly means
With both probes out the unit protects itself by cycling 3 minutes on, 3 minutes off.
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
Both probes are replaced and normal control confirmed.
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 refrigerator maintenance
Alpha Pro provides preventive and general maintenance for True refrigerators. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Water filter: replace on schedule or when prompted, using the correct filter for the appliance.
Interior and seals: follow official cleaning guidance; keep door seals clean and dry.
Stainless surfaces: clean in the direction of the finish with a mild cleaner; avoid abrasives.
Airflow: keep vents inside the cabinet unblocked and leave clearance around the appliance.
Professional maintenance
Inspection follows the appliance design
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Condenser area and ventilation
Evaporator and frost condition
Defrost system and fans
Door gaskets and alignment
Water system, ice maker, and filter
Drainage and condensation
Visible corrosion or moisture exposure
Temperature, sound, and operation
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: operation, airflow, water, controls, doors, installation, 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 refrigerators across San Diego
Alpha Pro serves True refrigerators 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.

Helpful answers
True refrigerator service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day True refrigerator 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 refrigerator?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
Does my True Residential refrigerator have error codes?
Not numeric ones - it shows plain-language statuses like Refrigeration Error or Compartment Probe Failure. Online P1/E1 code lists belong to True's commercial line and do not apply.
Why is only one side of my True side-by-side warm?
TR-42/48 models run dual compressors and dual evaporators - each side is its own circuit, and diagnosis is per-circuit rather than whole-box.
Where is the serial number on a True refrigerator?
On a gray tag on the interior wall, top left - on the big built-ins, near the freezer basket or top refrigerator drawer on the left wall.
Who actually builds True Residential?
True Manufacturing in O'Fallon, Missouri - the same company behind True's commercial refrigeration, which is where the stainless interiors and forced-air design come from.
Can you service the outdoor undercounter units?
Yes - they are UL outdoor-rated, and the visit starts with the power and ventilation checks outdoor installs actually fail on.
