What is the failure of the air heat exchanger and how to maintain it?
What we should do with air heat exchangers are:
(1) The control part of this heater is a precision instrument, so it should be handled gently and cannot be shocked or impacted.
(2) The cylinder part should be reasonably carried out during lifting and other operations.
(3) When it is stored, it is strictly forbidden to rain and damp.
Problem 1: The digital display does not work
The reason may be that the air switch is not closed or there is a problem with its control loop.
Problem 2: The temperature does not rise
The reason may be damage to the fuse or damage to the heater as a whole.
