OEM Carrier Furnace Transformer 120V/24V 40VA for Model PG9MTAV60100ABSS

This OEM control transformer (part # HT01BC117, superseded by HT680056) is the factory-specified replacement for the Carrier PG9MTAV60100ABSS gas furnace. The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, gas valve, and all low-voltage control circuits. When it fails, nothing works — the furnace will be completely unresponsive with no thermostat communication, no inducer startup, and no error codes displayed.

  • Specs: 120V primary | 24V secondary | 40VA rated | Foot-mount configuration | Basler Electric BE161840GDD equivalent | OEM part # HT01BC117 (current supersession: HT680056)
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage-regulation tolerances required by Carrier's IFC control board. Undersized or off-tolerance aftermarket units can cause nuisance lockouts, erratic thermostat behavior, or premature control board failure.
  • Install difficulty: 2/5 — Turn off power at the disconnect and breaker before touching any wiring. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all low-voltage wires before disconnecting. A typical technician completes this swap in under 20 minutes.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Directly fits Carrier model PG9MTAV60100ABSS and related PG9MTAV / PG9YAA series furnaces. Always verify your existing transformer's primary voltage, secondary voltage, and VA rating against your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — same-day shipping available on all in-stock orders.

How do I replace the transformer on my Carrier OEM Carrier Furnace Transformer 120V/24V 40VA — PG9MTAV60100ABSS?

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.
Is this transformer compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
