Incubator temperature/ motherboard issues

[Klaudia]

I have the little giant forced air incubator since 2021. I just started running it yesterday ( usually I do a test run for a couple days before I place any eggs this time I forgot) today I had to place my eggs in there. Since yesterday the motherboard has been acting up it’s showing the correct temp than switches to 188F and 88 humidity and keeps jumping back and forth. I noticed if I unplug the fan the display doesn’t switch back but temperature grows( I have 2 calibrated thermometers in there as well) to 103-104F than falls to 98-99f. At this point I’m thinking of just getting a plant heating mat... And I’m not sure if this will work??? The only replacement part I can find is the fan and the same incubator will be shipped by the end of May ( that’s when my quail are expecting to hatch) I don’t want to loose the eggs and birds what can I do to ensure safe hatching. I’ve never had this issue before and I only hatch 1-2 times a year so the incubator has only been used about 6 times.
Thanks in advance

Can you get an Incubator, from a store???
I do not have any recommendations to repair your current one.
I don't think a plant heating mat would give you the ideal temperature needed.
