---

### **1. Commercial Oven Not Heating Properly**

**Symptoms:** Food takes longer to cook, uneven heating, or the oven doesn’t reach the set temperature.

**Troubleshooting Tips:**

* Check the **thermostat calibration**—an inaccurate thermostat may need recalibration or replacement.

* Inspect **heating elements or burners** for damage or blockage.

* For gas ovens, ensure the **gas supply valve is fully open** and there’s no leak or pressure issue.

* Clean out any **carbon buildup** or food residue inside the oven that could affect performance.

**Preventive Tip:** Schedule regular thermostat and element inspections. Avoid using harsh chemicals that could corrode internal components.

### **2. Refrigerator or Freezer Not Cooling**

**Symptoms:** Warm temperatures inside the unit, food spoilage, or constant cycling.

**Troubleshooting Tips:**

* Make sure the **door is sealing properly**—check gaskets for cracks or wear.

* Inspect the **condenser coils**; dirty coils can block heat dissipation.

* Check for **obstructed air vents** inside the unit that may be preventing airflow.

* Ensure the **thermostat is set correctly** and functioning.

**Preventive Tip:** Clean condenser coils monthly and avoid overloading the unit, which restricts airflow.

### **3. Food Warmer or Holding Cabinet Not Maintaining Temperature**

**Symptoms:** Food gets cold quickly, inconsistent heat in trays or shelves.

**Troubleshooting Tips:**

* Test the **thermostat or temperature control unit**.

* Ensure the **heating element** is functioning—replace if not.

* Inspect the **power connection or breaker** if the unit is completely unresponsive.

**Preventive Tip:** Always preheat holding cabinets before loading food and clean them after each use to maintain efficiency.

### **4. Fryer Not Heating or Overheating**

**Symptoms:** Oil doesn’t reach temperature, fryer shuts off randomly, or oil overheats.

**Troubleshooting Tips:**

* Check the **high-limit thermostat**—it may be tripping too early.

* Inspect the **heating elements** or burner tube for buildup or residue.

* Verify the **oil level**—too little oil can cause overheating, while too much affects heating consistency.

* Reset the fryer using the **manual reset button** (usually near the controls).

**Preventive Tip:** Filter and change oil regularly and clean out crumbs or residue that can burn and damage the unit.

### **5. Dishwasher Leaving Residue or Not Cleaning Properly**

**Symptoms:** Dishes come out dirty, cloudy, or with soap residue.

**Troubleshooting Tips:**

* Clean the **filters and spray arms**—blockages reduce water flow.

* Check **rinse aid** and **detergent levels**.

* Inspect the **heating element** if the water isn’t reaching the required temperature.

* Ensure the **drain is not clogged**.

**Preventive Tip:** Rinse dishes before loading, and run a daily cleaning cycle with descaling agents.

### **6. Mixer or Food Processor Not Turning On**

**Symptoms:** No power, motor not spinning, or strange noises.

**Troubleshooting Tips:**

* Examine **motor brushes** if it’s an older model.

**Preventive Tip:** Avoid overfilling the bowl and clean blades and housing thoroughly after use.

**Symptoms:** Chilling cycle takes too long, or food doesn’t cool to the target temperature.

**Troubleshooting Tips:**

* Confirm the **doors are sealing tightly** and aren’t left open too long.

* Check the **evaporator fan** for functionality.

* Avoid **overloading** the unit—airflow is essential for rapid chilling.

* Clean the **air filters and condenser**.

**Preventive Tip:** Load in small batches and space items evenly to ensure consistent air circulation.

### **8. Gas Equipment Has Weak Flame or Won’t Ignite**

**Symptoms:** Burners won't light, flames are too low or yellow, or there's a gas smell.

**Troubleshooting Tips:**

* Inspect the **thermocouple** or **ignitor** for damage.

* Ensure the **gas valve is open** and there’s adequate supply pressure.

* Check connections for **leaks** using a soap solution.

**Preventive Tip:** Clean burners weekly and have gas lines professionally checked annually.

**Symptoms:** Coffee or tea isn’t hot, or the unit takes too long to heat.

**Troubleshooting Tips:**

* Inspect the **heating element** or internal thermostat.

* Check the **water supply connection** and descaling status.

* Reset the **thermal cut-off switch** if it’s been triggered.

**Preventive Tip:** Descale monthly and avoid leaving the unit powered on when empty.
