The dryer doesnt get hot enough to dry clothes

Pull the dryer out and remove the lint hose . Turn on the dryer and feel if there is good air flow and if you feel heat . If there is good air flow and heat , dry a load of clothes , to see if they dry normally .
If there is not good air flow , then the blower wheel is probably stripped and needs to be replaced . If there is good air flow and heat , then the problem is in the vent ducting , between the dryer and to where it vents to the outside . Dryer could be pushed back too far , causing the hose to " kink " , restricting the air flow to the outside .
Remember , a dryer either heats or doesn't heat . If no heat , then a dryer problem exists . If heat , but dryer does not dry , then a vent problem is the cause ( except for maytag , which the blower wheel sometimes strips out ) .
