Mobile Reefer (Refrigeration) Repair
A reefer alarm or changing temperature needs a clear service call. Have the unit details, alarm messages, temperature readings, and load contact ready before calling a refrigeration provider.

Build a useful service brief
Gather these details from a safe position. For a highway stop, follow your carrier's procedures and applicable warning-device requirements.
- Give the highway, travel direction, exit or mile marker, and a location pin if available. Describe access restrictions and whether a lane is blocked.
- Identify the commercial truck or trailer, whether it is loaded, and whether it is attached to the tractor.
- Give the refrigeration-unit brand, model, and serial or unit number if available. State whether it is single-temperature or multi-temperature and which zone is affected.
- Record the complete alarm number and message, setpoint, displayed temperatures and times, operating mode, and whether the unit is running or shut down.
- Have the carrier or load-contact number ready. Report any temperature deviation and confirm who authorizes repair or transfer arrangements.
Choose a provider for the unit
Ask whether the provider services this exact brand and model, can diagnose the alarm, and can work on a multi-temperature or standby-equipped unit if applicable. Confirm whether this location is workable and what would require a dealer or shop. If your fleet or warranty requires training or manufacturer authorization, confirm it directly. A general trailer-repair listing does not establish refrigeration capability.
Confirm timing, price, and authority
Ask for an arrival estimate, call-out and travel fees, diagnostic and labor minimums, hourly rate, after-hours charges, and taxes. Confirm whether parts or specialist visits are extra, accepted payment methods, what is payable if on-site repair is not possible, who approves further work, and when to expect delay updates.
Preserve information; avoid improvised repairs
Record alarms before discussing a reset with the technician. Alarm meanings depend on the unit, so use its official manual. Do not remove covers, reach near belts or fans, open refrigerant lines, or attempt electrical repair from this guide. Some units can start automatically; leave isolation and service to a qualified technician using the exact unit procedure.

FAQ
This guide cannot determine cargo condition or acceptance. Share time-stamped readings and monitoring records with the carrier or designated load contact, and follow load-specific instructions.
Do not assume so. Confirm the provider's refrigeration experience, brand and model coverage, equipment, and availability before authorizing a visit.
Call providers directly to confirm service fit, availability, price, and timing. RoadService.app is a directory and does not dispatch repair work.
