🔧 Lamona Hob & Samsung Integrated Oven – Electrical Fault Investigation & Repair
Another job completed today for a customer.
The customer was experiencing an issue with the electrics tripping and initially suspected that the Samsung integrated oven might be responsible.
I carried out insulation resistance checks on both appliances to identify the source of the fault.
🔹 Lamona 4-Burner Electric Hob
After testing, I identified that the hob was the cause of the problem.
- One solid hotplate was showing low insulation resistance, causing the electrics to trip.
- Two further hotplates were also deteriorated and no longer operating as they should.
- Three hotplates were replaced in total.
- Three control k***s were also replaced.
I removed the hob and transported it back to my workshop, where the replacement parts were fitted before returning and reinstalling it at the customer's property.
🔹 Samsung Integrated Oven
As the customer was also concerned that the oven could be contributing to the problem, I carried out insulation resistance checks on the Samsung oven.
The oven features a dual-element cooking system, fan-assisted heating and a divider function.
I checked the relevant heating circuits, including the upper and lower elements and fan-assisted heating circuit.
All insulation readings were satisfactory, confirming that the oven was not responsible for the tripping issue.
⚠️ Additional Electrical Observation
During the inspection, I also identified that the existing electrical connections behind the hob and oven could do with some attention.
The appliances were connected through an existing ceramic connector arrangement, with insufficient protection around the exposed earth conductor.
I photographed the existing wiring and advised the customer that a separate return visit would be required to tidy and properly enclose the connections using a suitable connection arrangement.
This is something I always like to point out rather than overlook.
The result: The faulty hob has been repaired, three hotplates and three control k***s have been replaced, and the Samsung oven has been tested and confirmed satisfactory.
Another example of why proper fault-finding and insulation testing are important. It's not always the appliance you initially suspect!
