There appears to be a known software bug that prevents the OTA sensor reading from being accurate. Typically the reading will be in the midrange. Mine was pegged to 54 degrees despite actual temperature.
Two people have reported contact with Meade in regard to this temperature reading error and both reported that Meade was working on a fix with expected results in 6-12 weeks from this date.
Other issues reported include a OTA temperature report that is pegged at the limit (typically 254*F).
If your OTA is pegged at the extreme then the likelihood is that the wires have pulled free from the sensor that is attached to the Collector Plate.

"I think you will find one or both the wires pulled out of the sensor on the temp sensor glued on the corrector. The wires get caught in the baffle ring slot. (Poor design) Happened to me when the focuser motors went haywire skewing the corrector, the temp will stay on max value. If you are careful you can solder the wires back on and it should read correct temp."
Pesse (I wish it was as warm as my OTA reports!) Mist
