Narrative:

We were cleared for takeoff on runway 3C at dtw. Shortly after throttle advancement, the right ice protection temperature high light illuminated. (Airfoil anti-ice system not in use). Suspecting a bleed air leak, we taxied back to the gate. Maintenance found no bleed leak, but did find a heat exchanger cooling for that was overheating and failing. At first the connection between the cooling fan and the air foil overheat light was not apparent, maintenance then showed use the close proximity of the 2 items and the reason for the triggering of the icl protection temperature high light became more apparent. I suggested that the incident be included in a monthly newsletter so other pilots would be aware of the connection. Supplemental information from acn 285833: maintenance sign-off of a mechanical problem may not be clear to people reading the fix at a later date. On the corrective action, they did not specify that the hot ground blower (fan) could cause an ice protection temperature high light.

Title: TKOF ABORTED.

Narrative: WE WERE CLRED FOR TKOF ON RWY 3C AT DTW. SHORTLY AFTER THROTTLE ADVANCEMENT, THE R ICE PROTECTION TEMP HIGH LIGHT ILLUMINATED. (AIRFOIL ANTI-ICE SYS NOT IN USE). SUSPECTING A BLEED AIR LEAK, WE TAXIED BACK TO THE GATE. MAINT FOUND NO BLEED LEAK, BUT DID FIND A HEAT EXCHANGER COOLING FOR THAT WAS OVERHEATING AND FAILING. AT FIRST THE CONNECTION BTWN THE COOLING FAN AND THE AIR FOIL OVERHEAT LIGHT WAS NOT APPARENT, MAINT THEN SHOWED USE THE CLOSE PROX OF THE 2 ITEMS AND THE REASON FOR THE TRIGGERING OF THE ICL PROTECTION TEMP HIGH LIGHT BECAME MORE APPARENT. I SUGGESTED THAT THE INCIDENT BE INCLUDED IN A MONTHLY NEWSLETTER SO OTHER PLTS WOULD BE AWARE OF THE CONNECTION. SUPPLEMENTAL INFO FROM ACN 285833: MAINT SIGN-OFF OF A MECHANICAL PROB MAY NOT BE CLR TO PEOPLE READING THE FIX AT A LATER DATE. ON THE CORRECTIVE ACTION, THEY DID NOT SPECIFY THAT THE HOT GND BLOWER (FAN) COULD CAUSE AN ICE PROTECTION TEMP HIGH LIGHT.
