Trane Electric Furnace

No heat, replaced the controller card. When the thermostat provides heat control fan will start and I am therefore assuming that the relay is sending power to the first coil to be coupled to the blower motor. What is the best next step? Measure the resistance of the heating coil, or pull the coil and how it is done on a Trane, which is 1 year. Thank you,

Perhaps nothing more than a heater relay. You will need to look and see the pattern that drives the heater relay. Find out if you have the control voltage of the relay, where appropriate ensure that the power line goes in depth over the heater. If so check the voltage to the heater and see if you have the 240v. If so and you do not heat you have a bad coil.
