hi Pearl! yes! i have an older carrier 58gs100-gb. the pilot is comin on, but the burners do not light. i jumped the thermostat to see if the blower works and it does! i was wondering what cud possibly be the problem. i didn't see a fna inducer on this model, and did not hear the gas valve opening.
JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?
Customer: not sure
