Question about Heating & Cooling

Open Question

Hi, Is it possible that I can source a replacement front flap for a Honeywell ST6400C programmer. I believe the part No is 42009012-001 as indicated on the inside of the flap. Basically the hinged lugs have broken on the flap. Please advise. Kind regards, Steve Wright 07743 129821 steviepw@btinternet.com

SOURCE: Replaced thermostat on FA4ANF030 with Honeywell model rth3100c does not work

4-wire typical wiring of a thermostat is: Y (Yellow) G (Green) W (white) and R (red). Inspect the thermostat to see if it has a jumper from R1 to R2. If not, put your red wire on R2. On a 5-wire thermostat you may have a blue wire. This will go to the common terminal (usually C but sometimes B) check the inline fuse in the air handler to see if it has blown. Replace it only after wiring the thermostat correctly.
