What tE3 / tE5 / tE6 / tE7 (Kenmore hybrid heat-pump) Means
The Kenmore hybrid dryer runs a heat pump alongside conventional heating, and it carries far more temperature sensors than an ordinary dryer as a result: tE3 for the heater thermistor, tE5 and tE6 for the compressor inlet and outlet, and tE7 for the evaporator inlet.
Common Causes of tE3 / tE5 / tE6 / tE7 (Kenmore hybrid heat-pump)
- A thermistor drifted out of its specified range
- Damaged wiring between a sensor and the main control board
- A refrigeration circuit not performing as the sensors expect
🔧 One Safe Check You Can Try
There is no useful owner check inside a heat-pump cabinet; what helps is noting whether loads take far longer than normal and whether the machine feels warm at the back, since both narrow the diagnosis.
⚠ Why You Shouldn't Go Further Than That
- A heat-pump dryer contains a sealed refrigeration system, and work on that circuit is a different trade from ordinary dryer repair.
- Cut power at the breaker before any panel comes away; these cabinets carry both mains voltage and a compressor circuit.
- Replacing a sensor without confirming the refrigeration side is behaving simply moves the complaint along.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
