Dish Overheated, Service Reduced to Protect Hardware
The STARLINK-OVERHEATED (Starlink) EV fault code means: Dish Overheated, Service Reduced to Protect Hardware. This is a serious severity code.
- Keep driving?
- Yes, but fix soon
- DIY difficulty
- easy
- Estimated cost
- $0-$50 DIY (shade structure, pole relocation, mount hardware). Professional installation of a new mount or shade structure: $100-$300. Starlink hardware replacement if unit is defective: covered under warranty if within 1 year, otherwise approximately $200-$599 depending on kit type.
A $30 car code reader can't do diesel. The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Common Symptoms
- Starlink mobile app shows the status message 'Overheated' on the main screen
- Internet speed drops dramatically or connection cuts out entirely during the hottest part of the day
- Dishy feels very hot to the touch on the back housing
- App Diagnostics screen shows reduced uptime or repeated short outages in a pattern matching peak sun hours
- Streaming, video calls, or uploads fail consistently between roughly noon and 5 PM in summer
- Connection may recover on its own after sunset or once the dish cools down
- Statistics tab in the Starlink mobile app shows high outage counts but no obstruction or other fault
Probable Causes (Ranked by Likelihood)
- Direct summer sun heating the dish surface above its thermal limit, common in TX, AZ, FL, and similar climates Very Likely
- Dish mounted on a surface that radiates heat upward (metal roof, dark membrane, concrete), compounding solar heating Very Likely
- No airflow around the dish, such as a flush mount with blocked venting or mounting inside an enclosure Likely
- Ambient air temperature exceeding the dish operating range (rated to roughly 50 degrees C / 122 degrees F ambient) Likely
- Dish tilt or orientation placing the back panel in direct sun for extended hours Possible
- Internal thermal management hardware (heat spreader or thermal paste) degraded on an older unit Less Likely
- Firmware bug causing incorrect temperature reporting or premature throttling on a specific hardware revision Less Likely
Step-by-Step Diagnostic Procedure
Open the Starlink mobile app and tap the status area at the top. If you see 'Overheated', note the time of day and current outdoor temperature. This confirms the fault is active, not historical.
Go to the Statistics tab in the Starlink mobile app and review the outage graph. If outages cluster during midday to late afternoon and clear in the evening, heat is almost certainly the cause.
Physically inspect where Dishy is mounted. Note whether it sits in direct sun all day, whether it is flush-mounted against a heat-absorbing surface (dark metal, asphalt shingles), and whether air can circulate around the back housing.
Check the back of the dish carefully. If it is too hot to hold your hand against for more than two seconds, the unit is thermally stressed. This is not a normal operating temperature.
Try providing temporary shade above the dish without blocking the sky view in front of it. A simple shade sail, board, or awning positioned above and behind the dish can drop surface temperature significantly. Test for 30-60 minutes to see if the fault clears.
If shade is not practical, check whether the mount can be relocated to a spot that gets afternoon shade naturally, such as a north-facing roof section or a pole mount near a building that blocks western sun after noon.
Check for airflow. If the dish is mounted flat against a surface or inside any kind of housing, move it so at least 2-3 inches of clearance exist around the back. Heat needs somewhere to go.
If the dish overheats even in mild temperatures (below 90 degrees F) or even with shade, the unit may have an internal thermal defect. Contact Starlink support through the app and request a hardware replacement. You will need your account details. No field repair is possible on internal thermal components.
Common Fixes by Vehicle

All Starlink hardware in hot climates (TX, AZ, FL, NV) Easy DIY
Overheated dishes throttle service and shorten hardware life. The dish has aluminum heatsinks but they're sized for moderate climates. In TX/AZ/FL summer with direct sun, internal temps can hit 50-60°C and the firmware reduces output. Solutions: (1) Provide overhead shade WITHOUT obstructing sky view -- a small white awning above the dish, or careful positioning under partial roof overhang that still gives sky view. (2) Reflective dish cover (aftermarket, white or silver, designed not to interfere with the antenna) -- ~$30-50 on Amazon. (3) Permanent relocation to a shaded yet sky-clear spot. Don't enclose the dish in a box -- it needs airflow and direct line of sight to satellites.
Labor: 30 min installFrequently Asked Questions
What does Starlink OVERHEATED mean?
It means Dishy, the antenna, has reached its internal temperature limit and is throttling or cutting your connection to protect itself from heat damage. This is a built-in safety feature. The dish is not broken, but it will not deliver full service until it cools down.
Will my Starlink connection come back on its own?
Yes, usually. Once the dish cools down, typically after sunset or if a cloud covers the sun long enough, service will restore automatically. But if you do nothing, the problem will repeat every hot day. You need to address the root cause or you will lose service every afternoon in summer.
How much does it cost to fix?
If the fix is shading the dish or adjusting the mount, it can cost nothing to about $50 in materials. A professional mount relocation runs $100-$300. If the dish itself is faulty and overheats in normal conditions, Starlink may replace it under warranty at no cost. Out-of-warranty hardware replacement is $200-$599 depending on your plan tier.
Can I put a box or cover over the dish to shade it?
No. Covering or boxing in the dish blocks the sky signal and will cause an obstruction fault on top of the heat problem. Shade must come from above and behind the dish, not in front of it. Think of an awning or sunshade positioned so the dish still has a clear view of the sky.
