I'm dealing with a Frigidaire FDE436RES1 dryer that tumbles and runs through the timed cycles without a problem, but will not heat on any setting. My wife reports that the top lid had been getting pretty hot during use lately, and it stopped heating altogether last week.
Here are the steps I have taken so far:
1. Tested wall outlet with multimeter on AC: 240V between the hots and 120V between each hot and the neutral.
2. Inspected terminal block where power cord enters dryer. All connections clean and secure.
2. Disassembled lint trap and removed a pretty big mass of lint that may have been blocking air flow. Cleaned lint trap, tube and outdoor vent. Ran dryer without vent tube. Still no heat.
3. Disconnected and tested following internal parts for continuity with multimeter set on Ohms XK1 setting:
a) Thermostat: needle moved to reading of zero
b) Thermal Limiter: also zero
c) Heating coil: zero. No breaks or weaknesses detected in the coil, though the metal pan and back panel near the top part of the coil appear scorched.
Please let me know what else I should be taking a look at in this dryer. It's from the mid 1990s, so I'm trying to go the DIY route for fear that calling a pro may cost more than the appliance is worth. Thanks in advance for your input.
