Adjustable Defrost Timer Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12851
Jlab Export is a leading Adjustable Defrost Timer Manufacturer,and suppliers in India
A defrost timer switches a frost-free refrigerator between cooling and defrost. During cooling it feeds the compressor, and at set intervals it changes over to the defrost heater, then back again. This adjustable timer is for domestic refrigerators running on 220–240 V, 50 Hz.

Fault-Finding Practicals on Defrost Circuits
Students first wire a bench defrost circuit: the timer, the Defrost Heater Glass Tube and the Defrost Thermostat in series with the heater. With a Digital Multimeter they find which timer terminal feeds the compressor and which feeds the heater. Then they set the timer to switch over and check that the heater circuit goes live.
The Dual-Application Commercial Refrigeration Training Unit has a defrost timer, an electrical defrost cycle and an electrical fault package. Teachers switch in faults there for students to find. A no-frost Domestic Refrigerator then lets the class trace the same circuit inside a real cabinet.
Frequently Asked Questions
How do I start a defrost to test the circuit?
Switch the timer over to defrost. The compressor should stop and the heater should warm within a minute or two. If it does not, check the heater and the defrost thermostat for continuity before blaming the timer.
How often should the timer start a defrost?
That depends on how often the door is opened and how humid the room is. Because this timer is adjustable, its setting can be matched to how quickly the cabinet frosts up in use.
What happens if the defrost timer fails?
If it sticks in cooling, the evaporator ices up and the fresh-food section slowly warms. If it sticks in defrost, the compressor does not run and the whole cabinet warms. The heater stays off once the defrost thermostat has opened.
Why does the refrigerator stop cooling for a while every few hours?
That is usually the defrost period. The timer stops the compressor and powers the heater, so cooling pauses while the frost melts. A short rise in cabinet temperature is normal. If the pause seems far too long or comes too often, check the timer setting and the defrost thermostat.
