Traulsen Refrigerators & Freezers — Cooling & Temperature Faults
Traulsen builds heavy-duty stainless steel refrigeration for professional kitchens, and many of the same units now anchor high-end home and catering kitchens. They are built to run all day, which also means small problems such as a dirty condenser or a worn gasket can quietly turn into warm product and failed compressors.
If your unit is holding above temperature, don't wait. Move perishable food to a working refrigerator and call us before the compressor runs itself out.
| Symptom | What it means | Urgency |
|---|---|---|
| Not Cold |
Cabinet Warm, Compressor Not Running
Failed start relay or capacitor, tripped overload, bad temperature control, or no power to the unit. Check the breaker and plug first.
|
High |
| Runs Nonstop |
Compressor Runs but Cabinet Stays Warm
Dirty condenser coil, failed condenser fan motor, low refrigerant charge, or a sealed-system restriction. Continuous running shortens compressor life.
|
High |
| Short Cycling |
Compressor Starts and Stops Repeatedly
Clogged condenser, overheating from poor ventilation around the unit, failing start components, or a faulty temperature sensor.
|
Medium |
| Uneven Temps |
Warm Spots or Freezing at the Back Wall
Blocked evaporator airflow from overloaded shelves, failed evaporator fan motor, or product stored against the air outlet.
|
Medium |
| Loud Noise |
Rattling, Buzzing, or Grinding
Fan blade striking ice or debris, worn fan motor bearings, or a loose compressor mount or panel.
|
Low |
A dirty condenser coil is the most common reason a Traulsen runs warm, and it is the easiest to prevent. Clean it every few months with a soft brush and vacuum, with the unit unplugged, and keep the intake and exhaust areas clear. Don't use a wire brush or a pressure washer on the coil.
Signs your Traulsen needs professional service
- Internal temperature climbing above safe holding range even after the door has been closed for hours
- Compressor humming, clicking, or cutting out within minutes of starting
- Oily residue on or around the compressor or refrigerant lines
Traulsen Defrost, Frost Buildup & Water Leaks
| Symptom | What it means | Urgency |
|---|---|---|
| Heavy Frost |
Evaporator Coil Iced Over
Defrost heater, defrost termination sensor, or defrost control has failed, so the coil never fully clears and airflow drops.
|
High |
| Water Inside |
Pooling Water on the Cabinet Floor
Clogged or frozen defrost drain line, so meltwater backs up into the cabinet instead of reaching the drain pan.
|
Medium |
| Leak Outside |
Water on the Floor Under the Unit
Overflowing or misaligned condensate pan, cracked drain tube, or condensate heater not evaporating water.
|
Medium |
| Sweating |
Condensation on Exterior or Door Frame
Damaged gasket letting humid air in, door left ajar, or high humidity in the room. Often cosmetic if the unit is holding temperature.
|
Low |
| Frozen Product |
Food Freezing in a Refrigerator
Temperature control set too low or failing, or product stored directly against the cold air discharge.
|
Low |
Never chip ice off the evaporator coil with a knife or screwdriver, since the refrigerant tubing is thin and easy to puncture. If you see frost on the back wall, unplug the unit, leave the doors open to thaw it, and call us. Frost almost always means a defrost component has failed, and it will return.
Signs your defrost or drain system needs service
- Frost or ice visible on the evaporator cover, fan, or back wall
- Repeated puddles inside the cabinet or under the unit after cleaning
- A sour or musty smell from standing water in the drain pan
Traulsen Doors, Gaskets, Lights & Controls
| Symptom | What it means | Urgency |
|---|---|---|
| Door Won't Seal |
Worn or Torn Door Gasket
Gasket is cracked, stiff, or pulled from its channel, letting warm air in and forcing the compressor to run harder.
|
Medium |
| Door Sags |
Hinge or Door Alignment Problem
Worn hinge, loose mounting, or an unlevel unit causing the door to drop and close unevenly.
|
Medium |
| Blank Display |
No Control Display or Unresponsive Controls
Loss of power, failed control board or transformer, or a tripped breaker. Check the outlet and breaker before calling.
|
High |
| Wrong Temp Reading |
Display Does Not Match Actual Cabinet Temperature
Failed or out-of-calibration temperature probe or sensor. Verify with a separate thermometer.
|
Medium |
| Light Out |
Interior Light Not Working
Burned-out lamp, loose socket, or a failed door switch.
|
Low |
A quick gasket check: close the door on a dollar bill. If it slides out easily anywhere around the frame, the seal is weak at that spot. Wash gaskets with warm soapy water, and replace any that are torn or stiff, because a leaking gasket is a common cause of frost and high energy use.
Signs your doors or controls need repair
- Doors that swing open on their own or do not latch firmly
- Display that is blank, frozen, or showing a reading that doesn't match the cabinet
- Visible gaps, tears, or mildew along the door gasket
Traulsen Appliance Service FAQ
Why is my Traulsen refrigerator not cooling?
The most common causes are a dirty condenser coil, a failed condenser or evaporator fan, a bad start relay or capacitor, or a defrost failure that has iced over the evaporator. A technician can pinpoint which one in a single visit.
Can I clean the condenser coil myself?
Yes, with the unit unplugged you can brush and vacuum loose dust from the coil. Do not use a wire brush, compressed air at close range, or water. If the coil is greasy or the fins are bent, call a technician.
How often should a Traulsen be serviced?
We recommend a professional inspection about once a year, or twice a year for units in heavy daily use. Service includes cleaning the condenser, checking the gaskets, testing the defrost cycle, and verifying cabinet temperature.
