Service and Check-ups
TARDISes should receive service every 500 to 1000 years. Most of a TARDIS's exitonic circuitry is accessible behind the roundels in the walls. The roundels will remain lit even when removed. Time Lords that skip this maintenance are likely to experience total system breakdowns and possibly even the destruction of their TARDIS. A TARDIS that is abandoned for over 3,000 years will break down and die from lack of maintenance. For this reason they should receive a check-up and overhaul every 3000 years. It takes about a month to overhaul a TARDIS.
When making modifications, it is important to shut down everything, except that which is not necessary to shut down. Operators are warned that some TARDISes gets quite upset when their parts are removed and used in other devices. They tend to hold a grudge about this and operate unpredictably for quite some time after being used as a technology donor.
