Danby Fridge Not Cooling? Compressor DG1-105 — Fix Warm Refrigerator Fast
A failed compressor is the most common cause of a completely warm or no-cool Danby refrigerator — when the compressor stops running, the entire refrigeration cycle shuts down. In most Danby-built refrigerators, the compressor is the heart of the sealed cooling system — it pressurizes refrigerant and drives it through the condenser and evaporator coils to produce cold air. When it fails, the fridge runs warm or stops cooling entirely, the compressor may click on and off repeatedly without starting, or it may be completely silent when it should be running. ⚡ Common failure point in Danby compact and beverage refrigerators after extended use or power surge events. Part DG1-105 is the genuine OEM replacement compressor that restores full sealed-system cooling in a single swap.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ The refrigerator powers on — interior light works and the unit has power
- ✔ The condenser fan and evaporator fan run normally when the compressor should cycle
- ✔ Refrigerant charge has been confirmed OK by a technician, or this is a compressor-only replacement
- ✔ ONLY problem is the compressor not starting, clicking off on overload, or fridge running warm with no cooling

🔧 Common Symptoms
- Refrigerator runs warm or fails to reach set temperature despite running
- Compressor clicks on then immediately shuts off — overload protector tripping
- Compressor is completely silent when it should be cycling — no hum or vibration
- Fridge interior light works but no cooling whatsoever — sealed system failure
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this compressor restores full cooling performance immediately after proper installation and refrigerant recharge.
📦 Part Details

Compressor replacement requires evacuating and recharging the sealed refrigerant system — this is a licensed technician job in Canada. While the system is open, inspect the start relay and overload protector — these small components fail alongside the compressor and cost very little to replace at the same time. Replacing them together prevents a repeat service call within weeks.
⚙️ Installation
Skill Level: ADVANCED — Requires licensed refrigeration technician (EPA/TSSA certified in Canada). Disconnect power before servicing. Recover existing refrigerant per local regulations before unbrazing the compressor from the sealed system. Install the new DG1-105, braze all connections, pressure-test for leaks, pull a deep vacuum, and recharge with the correct refrigerant type and weight as specified on the unit’s data plate. Confirm compressor starts and cycles normally before returning the unit to service.

💡 Pro Tip
The start relay is the most common reason a new compressor appears to fail immediately after installation — a faulty relay prevents the compressor from starting and can be mistaken for a defective unit. Start relays cost a fraction of the compressor price. Replace it during the same service call and eliminate any doubt about the root cause.
