Top Winter Reefer Emergencies in New England

Winter in New England can bring your refrigerated transport to a standstill. Sub-zero temperatures, freezing rain, and road salt can trigger failures that put your cargo at risk and cost thousands in delays. 

Thermo King Northeast provides 24/7 mobile emergency service from 3 of our locations, so your reefer is back on the road quickly. No waiting, no answering machines, just fast, on-site solutions.

1. Gelled Diesel Fuel

What Happens:

Diesel thickens between 10-20℉, clogging filters and lines. Reefers arriving from warmer regions may not have winterized fuel, leaving the unit unable to start.

Warning Signs: 

  • Engine cranks but won’t fire
  • Sudden loss of power
  • Cloudy fuel or wax in filters
  • Trailer temperature rising unexpectedly

Quick Tip: Always carry anti-gel additives on cold-weather routes.

2. Dead Batteries & Cold Start Failures

What Happens:

Cold reduces battery output by up to 50% while the engine needs more power to start. Smaller batteries are particularly vulnerable.

Warning Signs: 

  • Slow cranking or repeated clicking
  • Dim displays or electrical errors
  • Battery warning light
  • Unit worked yesterday but won’t start today

Quick Tip: Pre-winter battery load tests can prevent many cold-weather failures.

3. Overcooling & Frozen Cargo

What Happens:

Extreme cold can cause reefers to overcool, freezing sensitive cargo like produce, dairy, or pharmaceuticals. 

Warning Signs:

  • Return air colder than the setpoint
  • Frost or ice forming on cargo
  • Unit cycles excessively
  • Temperature fluctuations on logs

Quick Tip: Continuous run mode in extreme cold can prevent uneven temperatures.

4. Air Leaks & Failed Door Seals

What Happens:

Cold makes gaskets brittle. Gaps allow air to escape, forcing the unit to run constantly and compromising cargo temperature.

Warning Signs: 

  • Frost around door edges
  • Cracks or deformed seals
  • Unit running nonstop
  • Warm spots during loading

Quick Tip: Run a hand along closed doors to detect escaping cold air.

5. Mechanical Failures Triggered by Cold

What Happens:

Winter exposes weak components: brittle hoses, slipping belts, frozen condensers, compressor failures, and salt corrosion.

Warning Signs: 

  • Grinding or rattling sounds
  • Displayed alarm codes
  • Refrigerant or oil leaks
  • Loose belts or hoses
  • Unit running without cooling

Quick Tip: Frequent preventive maintenance reduces winter mechanical emergencies.
