We received a call from our customer Mr Wellburn in Dalgety Bay - Fife, who advised his Hisense American style fridge freezer had cooling issues! We took up the challenge of investigating and putting right this fault for Mr Wellburn. If your Hisense American style Fridge Freezer has cooling issues this might be worth a read...
On a recent service visit to this appliance I found the freezer was not reaching temperature? Hmmm! There was some cooling in there as, at a glance, I could see ice on the back panel. Let's get this bad boy to bits and have a look....go to image 3...

With the electricity supply safely isolated we can start work...
On removing the freezer evaporator cover I found the evaporator badly iced. This will reduce air flow causing an increase in cabinet temperature. But why?...

Prior to carrying out the relevant component tests, the evaporator must be defrosted. I carry a steamer on the van to do this

At the right hand side of this image you will see the jack plug connections. 2 grey wires, 2 orange wires, 2 black wires, 2 white wires (and a partridge in a pear tree)
They are as follows:
2 black wires = Evaporator defrost heater
Correct reading in ohms = 215 approx
2 grey wires = Thermal fuse
Correct reading in ohms = 0 approx
2 orange wires = Thermal fuse
Correct reading in ohms = 0 approx
2 white wires = Defrost Sensor
Resistance reading = variable with temperature
On successful completion of the above, I concluded that the defrost sensor was the at fault. Using a resistance to temperature chart I found the sensor out of calibration. A new sensor was fitted and the repair was a complete success.
Hopefully this post helps you further.
