So I've had constant issues with the internal long connectors, any remedies for this? It has intermittent issues specifically with the connection for the heater voltage. Reseating the connectors seems to temporarily solve this but it's a pain to do it every time I move it.

Try resoldering the connectors to the PCB.

Oh sorry, I meant the actual connection between the male and female plugs. I think some of the female connectors aren't gripping the pins, is there a way to fix this?
