    You can use a wire and jump from R to W on the thermostat if no heat jump from R to W inside the unit if no heat I would say it's a bad heat sequencer but its hard to say with out the voltage reading from the coil side of sequencer. If you have fuses inside the unit(line voltage side) you need to check them to see if one is blown.
