There are many things that can cause this so you need to isolate.
Measure the voltage coming from the top of the head. The voltage should represent the temperature "directly" like this:
0V=0C
5V=500C
200mv=20C
Then heat up the head so that it feels warmer (at least 30C) and measure the voltage again.
If the voltage is correct (voltage goes > 300mv) then the problem is in the cabling or underneath the UMO. If the voltage stays at 200mv then the problem is at the circuit board or the thermocouple. This is a first isolation step.
If you don't have a voltmeter, find someone who has one and have them show you how to use it (have them do the measurement!).

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

Did the thermocouple fall out? Check that first.
