Carrier Heat Pump Code Code 47

Carrier heat pump showing code Code 47 on the Infinity / Performance communicating system (outdoor unit)? The control reports no high-voltage (230V) supply present at the outdoor unit. The compressor and outdoor fan cannot run, resulting in no heating/cooling from the heat pump. Here is what it means, what you can safely check, and when to call a licensed CANRO technician in an urgent situation across Metro Vancouver.

What does Carrier code Code 47 mean?
The control reports no high-voltage (230V) supply present at the outdoor unit. The compressor and outdoor fan cannot run, resulting in no heating/cooling from the heat pump. This is an urgent fault that usually leaves you without heat or cooling — do not keep resetting it.

Likely causes of Carrier code Code 47

Tripped outdoor breaker or blown disconnect fuses
Outdoor disconnect switch turned off
Loose or damaged high-voltage wiring
Utility power loss to the unit
Failed outdoor control board

What you can safely check first

Check the breaker for the outdoor unit and reset it once if tripped
Confirm the outdoor disconnect switch near the unit is in the ON position
If the breaker trips again, stop and call a technician (do not open the unit)

What not to touch: beyond these checks, do not open the unit or touch the gas valve, wiring, control board or refrigerant lines. In BC, gas and HVAC repairs must be done by a licensed technician — both for your safety and to keep your manufacturer warranty valid.

⚠ Emergency signs: no heat in cold weather, a burning or gas smell, a tripping breaker, water around the unit, or a carbon-monoxide alarm. If you smell gas or a CO alarm sounds, leave and call FortisBC 1-800-663-9911 (and 911 if anyone is unwell) first — then call us for priority after-hours service.

Frequently asked questions

Is a heat pump worth it in Vancouver?

Yes. Vancouver's mild winters (average lows above -5°C) are ideal for cold-climate heat pumps. A properly sized modern heat pump can cover 100% of heating and cooling for most homes, cut heating bills by 30–60% versus electric baseboards or oil, and qualifies for combined BC Hydro, FortisBC and federal rebates.

What rebates are available for heat pumps in BC?

Review current Better Homes BC and utility program requirements for your property and equipment before installation. Amounts, application steps and permitted combinations vary. The Canada Greener Homes Grant and Loan are closed to new applications; previously approved applicants should follow their own file requirements.

Should I get a ducted heat pump or ductless mini-split?

If you already have ductwork from a furnace, a ducted central heat pump is usually the better choice for whole-home comfort. Ductless mini-splits are ideal for additions, suites, garage conversions, and homes without ducts (radiant heated houses).

How long does a heat pump last?

A modern heat pump installed by a qualified contractor typically lasts 15–20 years. Annual maintenance, regular filter changes and keeping the outdoor coil clear of leaves and debris all extend service life.

Do heat pumps work in cold weather?

Modern cold-climate heat pumps from Mitsubishi, Daikin, Carrier, Lennox and Bosch maintain rated capacity down to -15°C and continue producing heat (at reduced capacity) down to -25°C — far colder than Metro Vancouver ever gets.
