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.
The thermal relay may be bad.
Thermal Relay is defective.Thermal Relay is defective.
how to replace the thermal switch relay on a 1992 Honda civic lx
you cant theres no such thing what does the relay your looking for do
I am looking for the Thermal fusible link for the headlights on a 1998 Chevrolet Cavalier
no difference
110% of the rated current.
Sounds like the thermal relay is defective.
Bypass the relay and if the pump works the relay is bad.
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
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.
Check all the wiring and the Thermal Relay for the fan.
