OEM Carrier Control Transformer 75VA 208/240/480V → 24V for Model PH2PPB060000AB

This OEM control transformer (part# HT01BD242) is the factory-specified replacement for the Carrier PH2PPB060000AB packaged HVAC unit. The transformer steps down high-voltage supply power (208/240/480V primary) to the safe 24VAC used by the system's control circuit — powering the thermostat, contactor coils, and all low-voltage logic. When this transformer fails, the entire control circuit goes dark: your thermostat loses power, the system refuses to start on command, and you may notice a faint buzzing or burning smell near the unit's control panel. Replacing it with the correct OEM part restores full system operation immediately.

• Specs: 75VA capacity | 208/240/480V primary input | 24VAC secondary output | 50/60Hz | Factory-matched OEM tolerances for the PH2PPB060000AB
• OEM vs Generic: The OEM HT01BD242 is wound and insulated to Carrier's exact factory specification. Generic 75VA transformers often use thinner winding wire and lower-grade insulation, increasing risk of premature burnout — especially under the sustained load of a packaged commercial unit like the PH2PPB060000AB.
• Install difficulty: 2/5 — Shut off all power at the disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter (to confirm 24VAC output after install), wire nuts or spade connectors. Label all low-voltage wires before disconnecting the old transformer. Verify primary voltage tap matches your supply voltage.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PH2PPB060000AB packaged unit. Confirm your unit's supply voltage (208V, 240V, or 480V) and match the correct primary tap before installation. Cross-references with Bryant and ICP family units sharing the HT01BD242 specification.
