Introduction
The motor in a freezer compressors need a little more power to start up and get goingthen they do to keep running. They achieveget that extra power through a second coil that is energized when it'sthe freezer is first turned on, and then quickly turns offpower is cut to that second coil. Once spinning, the motor can keep spinninggoing with only onethe first coil.
The second coil is controlled by a starter relay. It works with a thermistor - a resistor whose resistance increases once it reaches a certain temperature, thereby cutting current to the starting coil.
If the starting coil burns out, you might notice your freezer not getting cold while compressor gets warm. oftenOften the thermistor will shatter, and you can hear it rattling around in the relay, but not always. You can check the relay with an ohmmeter. The BQP2-4.7 should read about 4.7 ohms at room temperature. Any other reading means it's probably failed.
For whatever reason, it's relatively impossible to get your hands on a BQP2-4.7, so we're going to repair one using parts from an easy to find and inexpensive similar relay - the QP2-4R7.
Conclusion
Put the relay into the
Put the relay back into your freezer and test it out.
Be aware that the freezer will only turn on if the disc is cool, so if it turns on at first and you turn the freezer off, it probably won't immediately turn on again because the thermistor is already warm. Give it 5 minutes and try again.

Summary
If your freezer stopped working, it could be because of a failed starter relay. TheIf your starter relay is a BQP2-4.7 is, then you'll have a hard to find,time finding a new one. Luckily butyou can easily repair it.
