My drier wasnt giving off heat so I thought it was the heating element so I replaced it but I still have no heat. I'm not sure what I should do next. Any thoughts?

Here are the parts
Replacement parts for WHIRLPOOL LEQ8857JQ0 | AppliancePartsPros.com

Here is the wiring diagram
http://www.servicematters.com/docs/wiring/Wiring%20Sheet%20-%203977704.pdf

First flip the breaker off/on a couple times slowly. Sometimes you can loose half the line without actually tripping the breaker and the heater requires the full 240 volts.
Better yet measure it at the plug.
L1 to L2 should be 240 volts
L1 ti Neutral and L2 to Neutral, both should be 120 volts.

If OK
Unplug the unit
Check that a wire has not burned off at the unit's terminal block
If OK
Check the heating element, it is not unheard of to get a bad replacement, should be around 10 ohms.
If OK
Check the operating thermostat and the hi-limit thermostats both should be 0 ohms
If OK
Check the thermal fuse this is the one on the heater, should be 0 ohms.
If it is blown also replace the hi-limit thermostat as this should have regulated the temperature so this fuse did not blow.
Only proviso on this is if the original heater was grounded, if it was then the thermostat cannot regulate the temperature and therefore blew the fuse so the hi-limit is probably OK.

If the fuse is blown check that the lint filter is not coated with fabric softener residue, check that the drum seals are OK, check that the seals in the heat path are OK, clean/check the blower wheel and clean/check the vent system.

Here is a good site with additional info

If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.

There is a good STICKY at the start of this forum about it's use.

Replaced heating element, fuse and thermostats, still no heat from the dryer? What’s the problem?
