Question about Precor C954i Commercial Treadmill
Any 30 series error code means that their is no communication between upper and lower boards.
The main Telco harness ( looks like a telephone or DSL wire) my have a bad or broken connection. Unplug unit and taken motor shroud off and check connections should be able to plug and unplug same goes with upper console. If this does not help then either call a local service provider or call Precor directly give them the Model# and Serial# for this unit. They should provide you with the additional info needed
