Changed batteries in thermo. Still not working. Just clicking. Please help! Model TCGD24S21S2XA
The clicking is probably a circuit board failure. The circuit board has a "micro-relay(s) that have a clicking sound. Normally its just a CLICK and the unit will start or compressor will start. So if yours is clicking this tells me its a micro-relay not making connection and continually trying to. If you have someone handy, have them inspect the board for burnt or damaged terminals or solders.
