OEM Carrier Transformer 75VA 208/240/480V to 24VAC for Model PH2PEB060000AA

This OEM Carrier transformer (part #HT01BD242) is the factory-specified control circuit transformer for the Carrier PH2PEB060000AA packaged heat pump unit. Its job is to step down high-voltage line power (208, 240, or 480V primary) to the 24VAC signal that energizes your thermostat, contactor coil, control board, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system refuses to start, and no low-voltage components respond. It is one of the first components to check when a unit has no thermostat response and no 24V at the control board.

• Specs: Input 208/240/480V primary | Output 24VAC secondary | 75VA power rating | 50/60Hz | Foot-mount chassis | OEM part #HT01BD242
• OEM vs Generic: This is a genuine Carrier OEM transformer wound to exact VA and voltage tolerances. Generic substitutes are commonly rated ±10% VA, which can under-power contactor coils or cause nuisance tripping of low-voltage circuit breakers over time.
• Install difficulty: 2/5 — Disconnect all power and verify zero voltage before touching wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24VAC output after install). Label all wires before disconnecting. A blown fuse or tripped breaker is often the root cause — inspect before replacing the transformer.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as the direct OEM replacement for the Carrier PH2PEB060000AA packaged heat pump. Verify input voltage on your unit's data plate (208V, 240V, or 480V) matches your supply before ordering. Have questions about fitment?
