Have you removed power from the furnace for a couple of minutes via the
switch next to the furnace? Some units "Lock out" when they encounter a
failure to start a couple of times. Until they are reset by removing
power, they will not come on again. This is a safety feature.

Next, check if the 24v A/C is present at the point the thermostat
switches it to when it is set to heat. You need to do some checking and
post more data in order to solicit help.

Hi,
Is the control voltage present?, the 24V AC coming off the transformer.
