That sentence is Miele’s own, read off its published support page for this condition rather than worked out from the outside. Everything below it — what the condition covers and what is worth doing first — is ours, written from what this equipment does in Miami kitchens. ### What this block of conditions is about Every dryer Miele sells in the United States now is a heat-pump machine, which means the condition on the display is usually about a circuit that has no equivalent in a vented dryer: a compressor, an evaporator and a condensate pump rather than an exhaust duct. ### What it covers What a published cause names is a circuit rather than a component, which is the single most useful thing to know before anybody orders a part. This one covers: - Refrigerant temperature sensor downstream of condenser open-circuited. ### Worth knowing before you call Miele publishes no owner step against this one, and neither do we. It is a condition for a technician rather than for the person standing in front of it, which is the honest reading of a code with nothing an owner can act on. Have the model and serial number ready and it becomes a short conversation rather than a long one. ### What a visit does first A sensor circuit reported short or open is measured before anything is replaced: a resistance at a known temperature against the maker's curve, then the loom back to the board. Roughly as often as not the sensor itself is sound and the run to it is not — a connector that has corroded in a humid South Florida laundry room or under a kitchen floor — and that is a much smaller repair than the part number suggests. ### Then what This is not a filter and not a setting. A Miele heat-pump dryer has a sealed refrigerant circuit, and its conditions point at the compressor, the evaporator or the sensors reading them — none of which is an owner’s job and none of which is improved by running the machine again. Twenty-four of the twenty-eight conditions this maker publishes for its dryers are in that group, which is the shape of a heat-pump machine rather than a sign that yours is unusual. Miele publishes this one for the heat-pump dryers. The [full Miele archive](https://mielemiami.support/error-codes/) has the other conditions, searchable, and on this make the same number appears on more than one machine roughly a third of the time, so the appliance above is part of the answer. We repair this equipment across Miami-Dade, Broward and Palm Beach.
