The bimetallic thermal relay consists of a small bimetallic strip that is heated by an element connected in series with the supply. When the current rises above a preset value, the movement of the strip releases a catch which opens the trip contacts.
In recent years more modern electronic relays are used which simulate the thermal overload. Many of these relays also incorporate a memory, i.e. simulates the temperature rise / cooling curve of the winding.

Why is your 98 Chevy Cavalier fan only works when the AC is on and sits still when off is there a heat sensor or a relay that might have gone bad?
The thermal relay may be bad.
95 sunfire overheating The only way to get the rad fan on is to turn on the air conditioner?
Thermal Relay is defective.Thermal Relay is defective.

How do you locate thermal relay on a 1997 cavalier?
you cant theres no such thing what does the relay your looking for do
Where is thermal relay on 1998 Chevy Cavalier?
I am looking for the Thermal fusible link for the headlights on a 1998 Chevrolet Cavalier
What is different thermal over load relay and thermally protected?
no difference
How do you set thermal relay for HT motor?
110% of the rated current.
What would keep the engine cooling fan from coming on in a 1994 Oldsmobile eighty eight The fan works if is is wired directly to 12 volt battery?
Sounds like the thermal relay is defective.
How do I know if I have a bad Fuel pump or fuel relay?
Bypass the relay and if the pump works the relay is bad.
How is thermal overload protection done in stator windings of motor?
one way is to use RTD sensor put inside the motor windings. The RTD sensor is connected to an electronic thermal overload relay. This type of relay can provide running temperature of the motor, on the electronic thermal over load relay display panel. RTD sensor is a wire wound resistor that changes resistance depending on the temperature
What is thermal overload?
The load current is made to flow through the thermal overload relay, which is actually a bimetalic strip. Beyond a prespecified current the bimetalic strip tend to deflect due to heat (thermal effect) thus cutting off the circuit and hence it acts as an over load relay protection.
1997 neon changed water pump thermostat fuse 30 is ok checked the fan Works turn on the car still overheat and the fan doesn't work?
Check all the wiring and the Thermal Relay for the fan.
