DRG Posted May 25, 2004 Share Posted May 25, 2004 I've got a Martin Roboscan 1220 that is constantly showing the hot error message and refusing to strike (even after the required 8 mins). It first started this morning, after the unit had been off all night (as normal). I've tried powering it down a couple of times since then, and still nothing. Anyone any ideas?

peter Posted May 25, 2004 Share Posted May 25, 2004 Possible a broken heat sensor. Can't remember exactly where they are in the 1220, but try putting a meter across it (the manual will probably give you a clue to its location). Link to comment Share on other sites More sharing options...
Guest lightnix Posted May 25, 2004 Share Posted May 25, 2004 I agree with peter, check the sensor. All that any error message means is that the sensor has tripped and in many cases it's the sensor itself that's at fault. Link to comment Share on other sites More sharing options...

DRG Posted June 1, 2004 Author Share Posted June 1, 2004 I was thinking of putting a hammer in.... Link to comment Share on other sites More sharing options...
dominicgross Posted June 1, 2004 Share Posted June 1, 2004 Hammers may strike, but I dont think they will work nearly as well a lamp. :D Link to comment Share on other sites More sharing options...
Paul J Need Posted June 1, 2004 Share Posted June 1, 2004 I was thinking of putting a hammer in.... Seriously Some of Robe's do the same........... the lamps has usually blown. Link to comment Share on other sites More sharing options...
DRG Posted June 2, 2004 Author Share Posted June 2, 2004 It's not the lamp, the one inside when the problem occurred is only a few weeks old, and I changed it anyway, just in case, and still no luck. Link to comment Share on other sites More sharing options...
Guest lightnix Posted June 2, 2004 Share Posted June 2, 2004 Check the connections to the sensor and the continuity down wires which connect it to the circuit board. If there is a break in the wire, or the connection is loose, that might simulate a high temperature reading. Link to comment Share on other sites More sharing options...
