One receiver pcb of 433.92 MHz has absorbed moisture and works when heated. So I want to bake it in a heated oven. Only one component I see that can be of issue is the adjustable inductor. How much temperature should I set and how long should I bake it.
Thanks in advance.

Best is keep in sunlight for a day, but don't forget to bring it back home before evening.
btw, How many PCBs are you dealing with such problem? and how do you know that its a moisture problem. did you heat any before ? sometimes with such tuned circuits, heat deviate the values which can make it work.

It is the car central locking remote receiver, one off.
It is only the coil that I am worried of and with my place(Goa) having humidity above 90% always, this usually is the problem after 2 or 3 years.
I even remember MW oscillators failing for the same reason.

Hi,
After having dried your PCB, have you considered giving it an application of conformal coating? You would need to mask any areas that may be affected by the product before applying, especially switches, buttons and battery contacts.
