Hello. I will briefly state all of the possible reasons why your dryer is slow but I will first say that the common reason under the circumstances you state is that the vent pipe is either partially clogged with lint, or partially blocked, or it has more bends and turns in it than you had in your previous residence. I would begin by pulling the dryer out, removing the vent pipe and checking inside the back of the dryer and in the vent pipe all the way to outdoors.
It normally takes about 45 minutes for a dryer to dry a full load. If your dryer is taking more than an hour, check these.VentHeating elementInternal ductworkCycling thermostat
Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance.
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace it.
Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum, contact a qualified appliance repair technician.
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.
