I had the same problem with the Reef Keeper lite, and my MH was shutting off when the little fan was coming on. Sometimes the unit would freeze and there goes everything dead, no pump, no heating, nothing, until I reset it.

I unplugged the MH from the bar and put it on a timer instead and it worked ok from there.

I solved the problem definitly and bought a Reef Angel...Best controller I ever got. I did not find the Reef keeper reliable and I thought it was even dangerous since it was stalling my tank when it was freezing.
