On our honeywell trolatemp universal minizone zone 1 and zone 2 lights are green. The purge light is flashing. Heat light is red and both thermostats are set at 74 and the temperature inside is 70 degrees, why isn't the furnace turning on?

Chances are it's a bad daamper. You can bypass any tstat by wiring red green and yellow together. Bypass the tstat, if still blinking you'll know it's the damper. You can then swap that damper to another zone and be sure the new zone then starts flashing.

Be sure all zones are calling for cooling. Press the purge override and verify air flow on all zones. If one is still not working verify the board is sending voltage to that damper. A meter is a huge help but if all lights are on chances are the damper is stuck. You should be able to free it up but it will just happen again. Either replace damper motor, replace damper or if you can figure out if it is a "spring open" damper, get it open and unhook the wire to that zone. This will keep it open at all times because it can not "power close". Provided that zone CAN stay open all the time. Keep me posted!!

If you have electric heat you must make sure that is what your tstat is set up for. Possibly setup for gas

i have honeywell system and zone 3 is off and purge light flashing and i have heat in all rooms except for my daughters room??? please HELP

It is a discharge temperature sensor and should be located in the duct after the coil. It should be just before the bypass damper.

On the zone damper motor, there should be a little lever allowing you to open the damper for emergency heat. Probably a bad zone motor or connection.

turn off the mains, remove the unit from its base, see if it has a

because it dosent have a duct sensor - should not be a problem
