Blizzard is a brand distributed in the UK (by Pentland) offering affordable cake display fridges in various sizes (e.g., countertop round displays, upright glass cabinets). Blizzard units generally have straightforward controls. Common issues include temperature fluctuations (often due to environment or loading) and basic electrical problems.
Typical Faults & Diagnosis: If a Blizzard cake display is not cooling properly, ensure it’s placed correctly – away from direct sunlight or heat sources that could overwhelm it. These units are designed for ambient <= 25-30°C. Check the plug and fuse first if there’s no cooling at all – it seems obvious, but many service calls stem from power issues. Ensure the socket works (test with another device) and the fridge’s plug fuse (13A) isn’t blown. Next, verify the thermostat dial or digital setpoint – Blizzard displays often have a preset temperature; user error in setting (or an accidentally bumped dial) can lead to “not cooling” complaints. If the fridge runs but struggles to reach set temperature, consider if a large batch of warm cakes was just loaded – these units need time to pull down temperature after loading. Also, check that the doors/sliding panels are fully closed; even a small gap can raise internal temperature (many Blizzard models don’t have a door alarm, so it might go unnoticed).
For continuous running (compressor never cycles off) and still poor cooling, suspect the condenser or ventilation: ensure the unit has space around it and the condenser coil is clean. An overworked, hot compressor indicates either a dirty condenser or a refrigerant issue – feel the sides of the unit; if they are excessively hot, unplug and inspect/clean the condenser. If after cleaning, the problem persists, the refrigerant charge might be low (from a leak) and you’ll need a refrigeration engineer. Water pooling in or under the cabinet is another common issue: check that the cabinet is level (use adjustable feet) and that the drain hole and drip tray are not blocked. Blizzard’s user manuals suggest emptying the drip tray and clearing drain lines if leaks occur, and defrosting the unit if ice is obstructing drainage.
Blizzard’s digital displays, when present, may not show detailed error codes (some models just have thermostat knobs). If your model has a controller (like the Blizzard BZ-CD400R has a digital control), it likely uses codes similar to generic ones above (E1, E2 for probes). The Blizzard instruction manual provides a simple troubleshooting Q&A: e.g., “No refrigeration – Is the plug in socket well? Is the fuse broken? Is there power?”. And for “Unsatisfactory refrigeration – Is there a heat source nearby? Does the door close well? Is there too much food blocking air flow?”. These hints align with general best practices.
Fault Code Table – Blizzard: (for models with digital control; otherwise see checklist below)
| Indicator | Likely Meaning | Advice |
|---|---|---|
| Compressor LED blinking | Thermostat off / reached temp | (No specific code) If the compressor indicator blinks but unit warm, thermostat might be set too high (or turned off). Action: Lower the temperature setting. |
| No lights or display | No power to unit | Unit is off or not getting power. Action: Ensure power switch on (if any), plug firmly in socket, check fuse and mains supply. |
| Unusual noises | See “Noises” below | Rattling -> unit not level (adjust feet); Buzzing -> compressor strain (clean condenser). Persistent loud noise could indicate fan or compressor issue – call engineer. |
| (No specific error codes on basic models) |
Blizzard Troubleshooting Checklist: (Before calling for service, go through this list):
- Is the power on and the unit plugged in? (Check outlet and fuse).
- Is the thermostat set to a cold enough temperature? (Adjust if needed).
- Have you cleaned the condenser recently? (Do so if dirty).
- Are all ventilation holes clear? (No boxes or walls blocking intake/outlet vents).
- Is the display fridge level? (Use a spirit level; adjust feet to eliminate rattles and ensure proper drainage).
- Do the door seals seal properly? (Clean gaskets; if torn, have them replaced to prevent warm air ingress.)
- If there’s a water leak, is the drain tube clear and the drip tray empty? (Defrost ice build-up if present).
If all checks are okay and the fridge still misbehaves, it’s time to call a repair service in the UK – Blizzard units are serviceable by any commercial refrigeration engineer, and parts (like thermostats or fans) are readily available.
