you guys have been grat and answered every question and problem i have ever had.... but i seem to have another one. i have a 1991 whitfield renisance and i have had alot of problems with it but i have been able to fix most of them, i have recently replaced the motor and my newest problem is that my stove has 5 settings from low(1) to high(5). if i leave the stove on 3 the outside gets really hot to the touch and the stove shuts down. i do not have a fresh air line to the stove from outside but i am considering installing one if it will keep the stove cool enough to work like it used to. any ideas on why my stove is getting so hot?
