By overheating which will cause a change in the thermostat materials construction.
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
the thermostat used to control the heater and after we select the four pole switch to some number the thermostat start connect the power to the heater at the same time the heater start to heat and when we select the switch to zero position the heater not work
Your radiator may be running low on fluid. Failed thermostat, damaged heater valve, blocked heater core/heater hose or worn out water pump. it could be a couple of things like the themostat or the heater core .
When the thermostat and radiator were replaced, coolant could have dripped into an electrical connector or a sensor could be disconnected or damaged. Check the temperature sensor and crankshaft sensors first.
Someone turned up the thermostat, or the thermostat has failed. The thermostat tells the heater what temp to keep the water at.
no heat can be caused by,blocked heater core insufficient coolant in engine blocked heater hoses from engine to heater core bad heater thermostat bad thermostat in engine bad heater control switch
The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
heater not hot
Check the thermostat.

No, BUT they do have an AQUA stat
What type of thermostat (there are several, the commonest is a rod)?
