¶ What it is
HMS_0300-9000-0001-0004: Chamber heating failed. The speed of the heating fan is too low.
¶ Error message
HMS_0300-9000-0001-0004: Chamber heating failed. The speed of the heating fan is too low.
¶ The cause of the error
The chamber temperature control module needs a fan to bring hot air into the chamber. This error means that the fan speed is lower than normal and therefore can not heat the cavity to the predetermined temperature.
¶ Solution
After powering off, check the cable connector of the chamber temperature control module's heating fan, reconnect it properly then turn on the power and set the cavity temperature to 60°C. If the error is no longer reported, the problem is fixed.
If the problem can not be solved after taking the above measures, please take a video of the issue and then contact the support team.
