Abstract: The device provides the possibility of feeding test signals to a thermoelectric module by virtue of the use of controllable switches and also makes it possible to increase test criteria and to detect faults and the causes of said faults at early stages outside of the use process of the thermoelectric module (TEM), as well as in periods between use. This technical result is achieved in that the device comprises a DC source, a measurement circuit, a first, a second, a third and a fourth controllable switch, which are used for feeding test signals and are switched on and off by a temperature controller. The first and the second controllable switches are used for connection to the DC source, and the third and fourth switches are grounded with the possibility of switching from the third controllable switch over to the first controllable switch and from the fourth controllable switch over to the second controllable switch.
