Error E05 on Hoover : Compressor start relay fault. Follow the troubleshooting steps below to diagnose and fix this refrigerator issue. ## What Error Code E05 Means on a Hoover HADN6182NFK E05 on the Hoover HADN6182NFK fridge-freezer indicates the compressor is not starting. The compressor requires a start relay (PTC relay) to provide the initial current surge needed to start the motor. If the PTC relay fails, the compressor attempts to start every few minutes, produces a click, and shuts down. When E05 appears, the Hoover refrigerator pauses normal operation to protect internal components from potential damage. Not every E05 fault requires a professional engineer — many are resolved through careful inspection and routine maintenance. Work through each diagnostic step below in sequence, starting with the simplest check, to identify the root cause efficiently before considering part replacement or arranging a service call. ## Symptoms - E05 on display

• Click every 3–5 minutes from compressor area
• No cold air; warm fridge and freezer ## Common Causes - Compressor start relay fault ## Tools You May Need - digital multimeter
• replacement PTC relay ## Step-by-Step Repair Guide | Step | Action | Result | |------|--------|--------| | 1 | Unplug fridge. Pull fridge away from wall to access the compressor at the bottom rear. | Compressor accessible — continue to step 2 if the issue persists. | | 2 | Locate the PTC relay — a small cube or cylinder plugged into the compressor side pins. | PTC located — continue to step 3 if the issue persists. | | 3 | Remove PTC and shake it — a rattling sound confirms the internal component has broken. | PTC tested — continue to step 4 if the issue persists. | | 4 | Test PTC with multimeter: should read ~5–20 Ω. OL or 0 Ω confirms fault. | Resistance measured — continue to step 5 if the issue persists. | | 5 | Fit new PTC relay, restore power, wait 5 minutes for compressor to start. | Compressor running — if the fault remains, contact a qualified technician. | ## Safety Precautions Unplug and wait 5 minutes before touching the compressor — it can retain heat. Never attempt to open the refrigerant circuit. ## Estimated Repair Time and Difficulty Most refrigerator error code E05 faults can be assessed and addressed in 30–90 minutes using the steps above. The diagnostic process requires only basic tools: a multimeter and standard screwdrivers cover the majority of checks described here. If a replacement part is required, allow 1–5 working days for delivery. A trained technician with access to the correct diagnostic equipment will typically resolve this type of fault within a single service visit. ## When to Call a Technician Contact a Hoover authorised service technician if: the fault persists after following all the steps above; if PCB-level or refrigerant-circuit work is required; or if you are not comfortable working with electrical or mechanical components. When calling, have the full model number, the error code displayed, and a brief description of any sounds or symptoms you noticed before the fault appeared — this helps the technician prepare the correct parts and tools. ## Frequently Asked Questions Q: How long does the PTC relay last? Typically 5–10 years. Frequent power cuts can accelerate PTC failure. Q: Is PTC relay replacement a DIY repair? Yes — it is a plug-in part requiring no tools or soldering. One of the easiest fridge repairs. Q: If the PTC is good, what else could cause E05? A failed compressor overload protector, faulty start capacitor, or a seized compressor motor — these require a refrigeration engineer. ### Is it safe to keep using my Hoover with error E05? If error E05 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the refrigerator with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error E05 on a Hoover ? Repair costs for error E05 on the Hoover refrigerator depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Hoover-authorized service provider for an accurate estimate based on your specific situation. ### What does error code E05 mean on a Hoover refrigerator? Error code E05 on Hoover refrigerator models indicates Compressor start relay fault. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed.
