What Service Light On means

On JennAir freestanding and undercounter ice makers such as the JIM158 series, the service light shows when the ice maker needs service. The first step is to turn the ice maker off and back on. If the service light comes on again, that means a real service call is needed. The light does not say which part is the cause.

Common causes of Service Light On

  • Temporary glitch that a power cycle can clear
  • Water supply or drain problem the unit detected
  • Cooling or ice-making system needs attention
✓ One safe check you can try

1. Turn the ice maker off, wait one minute, then turn it on. 2. Check that the water valve is open and the supply line is not kinked. 3. Make sure the condenser grille is clear of dust and nothing blocks airflow. 4. Check the drain hose for kinks. 5. If the light returns, call us.

! Why to stop there
  • The light covers many possible causes, so testing is needed.
  • Opening cooling parts requires a trained technician.
  • A power cycle only clears a one-time glitch.
  • We quote in writing before work and give a 30-day workmanship warranty.
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.

Service Light OnService Light On questions
What if the service light goes out after I restart?

A one-time glitch may have cleared. Keep an eye on ice production and on the light for the next few days. If the light returns, the ice maker needs a service visit and we can book one.

Does the service light tell me which part has failed?

No. It is a general alert, so it cannot name a part. We use the unit's behavior, the water supply and cooling checks to find the cause, then give you a written price before any repair.

Can I keep making ice with the light on?

If it still produces ice, you can, but a returning light means the problem is real. Waiting can lead to a bigger repair, so call us.
