Hi all,

I have a late-70s/early-80s vintage Whirlpool Imperial 70 dryer which has been going strong for 40+ years. However, in the last few years, it's gotten so that it often takes 2 runs — upwards of 2-2.5 hours — to dry a load, even on high heat. We're good about keeping the lint filter clean, but aside from that, does anyone have suggestions on what we might be able to do to make it run better? Or is it time to throw in the towel. (Or throw the towel into a newer dryer? ;-)

Many thanks in advance!

Heating Element (if this is an electric dryer)

It is possible that one of the heating elements is burned out or not functioning.
I remember this happening on our 1960's Whirlpool Imperial electric dryer.
Once the element was replaced, drying times were back to "normal".
A faulty thermostat could be another possible cause.
 
Flexible vent

I see you have the plastic vent. My sister had the same complaint and when I checked, the vent hose was nearly blocked! Yank it out and replace it with rigid aluminum 4” pipe. Also, pull the back off and vacuum out any lint. Should solve the problem.
 
You might want to look at the back of the drum and check to see if there is a gap between the drum and the bulkhead. You might need new rollers and maybe a drum seal. Also check the assembly at the front of the drum to make sure the Delrin ring and seal assembly is still good.
 
Something else to check.  Remove the lint screen and hold it under a faucet with the recessed side up like a dish to see if water goes through it. They can clog up with fabric softener use, especially the dryer sheet kind. If water does not run through it, it is clogged and you probably need a new one because it looks sorta fried already and clearing one of those is a big job. If you decide to clear it yourself, you need solvent. It is more of a job than detergent and water can tackle.
