I have a Reptipro 5000 and last season it messed up on me! It will not heat up , it will cool down and the fan would come on but it wouldn't get above room temperature and I think either the temperature gage is messed up or the heating element used is . I did go ahead and buy a Reptipro 6000 for this season and I love the thing , but would like to have my other one up and running to so if you have any issues like this and you know what to do please tell me ! Thanks !
