This permits the defrost cycle to be checked out in warmer weather conditions without the outdoor temperature having to fall into the defrost region. In order to terminate the defrost test, the SEN JMP jumper must be removed. If left in place too long, the compressor could stop due to the high pressure control opening because of high pressure condition created by operating in the cooling mode with outdoor fan off.
