Sub-Zero Classic BI Code 45-L-01: Accent lighting short

What 45-L-01 means

When a Classic BI unit such as the BI-36UFD/S shows 45-L-01, the accent lighting circuit has a short. The control detects too much current on that circuit and shuts the lights off to protect the board. The accent lights go dark, may have flickered before failing, and stay off until the short is found. Everything else, including cooling and ice, keeps working.

Common causes of 45-L-01

Shorted accent light strip
Pinched wire under trim
Moisture at the light connector

✓ One safe check you can try

1. Look for water or condensation near the accent lights and dry it. 2. Keep the door closing gently so trim is not knocked loose. 3. Avoid pressing on the light covers. 4. If you notice any burning smell, turn off the breaker and call us.

! Why to stop there

Short circuits can heat wiring.
Lights are mounted behind trim panels.
Repairs need matching LED assemblies.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

45-L-0145-L-01 questions

How is this different from 45-L-00?

45-L-00 means the accent lighting circuit is open, while 45-L-01 means it is shorted. A short draws extra current, so the control shuts it off.

Is it safe to keep using the refrigerator?

Yes, as long as there is no burning smell. The accent lights stay off because the control has cut power to them, and the unit keeps cooling normally until we find the short.

What is involved in the repair?

We locate the short, replace the damaged light or wire, and test the circuit. You approve a written price first, with our 30-day workmanship warranty.
