Overview

This genuine OEM 40VA control transformer (ICP/Tempstar part #1172810) powers the low-voltage control circuit on the Tempstar T9UHX060F12A2 gas furnace. It steps the 115V line voltage down to the 24V needed by the thermostat, control board, gas valve, and ignition system. A 40VA rating provides ample current for the furnace's control loads. When a transformer fails — usually from a control-circuit short, a shorted gas valve, or simple age — the entire 24V system goes dead: the thermostat blanks out, the blower and ignition won't energize, and the furnace will not respond to a call for heat. Installing this exact-replacement transformer restores full control power.

My thermostat has no power. What failed?

Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
