I am trying to find out which componet of a industrial sized lennox furnace is not operating. although all the componets look impossible to tell apart as a regular home gas furnace. The furnace will go through one heat cycle blower motor will shut down but inducer keeps blowing constanly. if I turn digital thermostat rotten and back on inducer spins but no gas is turned on to the component, if I switch the breaker off later back on the section will fire up and work though one heating cycle, is the problem my circuit card or digital thermostat, or something else? gratefulness.
Answers: Your High-limit may be causing the element to lock out,when you shut off the power ,you break this lock out and allow another cycle.
Your blower motor is tripping the breaker. Either the motor is too big, the breaker is too small, the motor have a short, the motor is dying due to dust or age, or your breaker is breaking.
