i have gqf 1270 cabinet incubator. i fired it up for the season a few days ago, andi am having temp problems. my front therm i can adjust but i will only go to about 95 degrees and not higher, i turned off my front therm, and tryed my back therm and temp doesn't go above 95 degrees. i think it is my heating element but not shore. i have never had to replace anything or fix anything on it. so not 100% on what i need to replace. thought about replacing the heating element and my front therm. but i say the price on them and if i don't need one right know i will get on at the end of the season and replace it them. also the model # for my front therm is 3140 and i cant find it, is the model# 3255 multi-turn therm the same thing? it would be great if i could get a little info before i start replacing parts that i don't need to and end up with putting a lot of money into it.
