Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
I have a honeywell furnace that the fan blows but theres no hot air. it stays at 58 when i have it set to 70. The burners are cooled and weve tried restarting the gas and theres still nothing. the model number we have is sv9500m
The sv9500m units are notorius for having cracks in the solder connections where the 4 wire plug socket attaches to the board in the gas valve. A short term fix or test is to apply pressure to the wiring by twising it, then try a relight. If it works you have a loose solder connection. To repair this (you assume all liability- there is no room for oops here)- remove 2 small security torx screws holding the plastic cover on. Remove only the half of the cover with the on/off switch sticking though it. It should just lift off. you may have to move it around a little no forcing. The solder spots are now accessable. check & resolder the connections where the 4 wire main connector hooks to the board- put the cover back on & test it. done.

Well first off honeywell does not make furnaces.all a home owner should do when dealing with any type of troubleshooting is what the manufactorer tells them to do in owners manual.heating systems can be very simple or complex but all have the potential to go boom so if your not sure call a professional
