Gas and Oil Home Heating Furnaces - Electric Baseboard heat

A tenant of mine has electric heat throughout his apartment. There are separate controls in each room (ie thermostats). All work except the double unit in his living room which is controled by a single thermostat. The tenant says that it will go on once in a while but it is in no way heating sufficiently.

I just checked it out myself and when I turned the temperature all the way up I noticed only a slight hint of warmth coming from the heater.

Is this a situation with the thermostat? Or is this something more involved like electrical?

I only recently bought the house, don't know much about the heaters besides that they are baseboard attached to the wall and that the thermostat is on the wall at chest level. The walls are plaster and therefore the wires are somewhere in the walls.

Can anyone give some advice?

Thank you,
Jeff

Jeff:

In order to check this out you will need an electrical multimeter to track down the problem.
You would first check for voltage going to the heaters from the thermostat and then be able to check the limit thermostat in each heater.
