Does anyone know a reputible dealer that sells parts for Thetford cassette toilets. I think the control panel has gone out on mine. Push button to rinse, nothing happens. Handle is fine so we just use a little water bottle. Anyway, I've changed both the five amp fuse which is probably for the pump and also the 3 amp fuse which I'm pretty certain controls the panel. I have the 800# for Thetford and may call them Monday. But appreciate any input here. Thanks.
