Final update. A properly trained engineer came out and diagnosed it as a blockage in the cooling system. Asked him what can cause this in a closed system, and he said the oil from the compressor can seep out over time into the drier and restrict the flow. He unblocked it, replaced the drier, re-gassed the system, and all working now !
Yes, I think you are correct. Bit like anything these days, you start off at Level 1 support and then move up the ladder over time. Just very frustrating for the customer.
I didn’t think it was going to bode well when he walked through the door armed with just a drill-type powered screwdriver and a laptop in a hard case.
Will update as we move along
Guy from Hotpoint tipped up this morning. They need to send in a “gas” (refrigerant) man as he’s not trained on that area ! He ordered a new compressor as the current one is hot while it was running. Maybe his training should tell him that these do run hot as a result of what they do
. He thought there might be a “blockage” in the line to the wet wall coils. I’m not sure how a blockage can occur on a closed system after it has been running this long, but there you go. Maybe I’m missing something….Maybe, and as you say, it is all buried inside the appliance. I have booked a service call for Thursday. Will update this post afterwards so that other people might benefit from it. Thanks !
Update – Purchased a fridge / freezer thermometer. Fridge temperature is 14 degrees !!, freezer is -25 degrees.
Thanks for your input in this. I guess I need to get Hotpoint in to take a look at it, unless anyone else can provide any additional input. Was just wondering if there was any testing I could do prior to calling them in, hence the post.
Thanks for the reply. The output pipe from the compressor is hot, as expected. This pipe then disappears up inside the back of the appliance, before it comes back out again into the exterior cooling radiator at which point it is warm. At the other end of the cooling radiator, it is room temperature. The radiator is dust free.
If the freezer wasn’t at -18, would the compressor keep running all the time ?
From the attached photo, I am not sure what the small bulbous device is at the end of the black pipe, which is at the end of the radiator coil. The other copper pipe coming back from internally back to the compressor is quite cold.
I guess I need to get a fridge/freezer thermometer to check the temperatures.
