Hi, I have a Whirpool dryer Its around 5 years old. One day the heat just quit working everything else runs just not heating to enable a fast dry. I replaced the fuse after having it tested at a local shop along with the heating element (element tested fine) that fuse blew after several uses. I returned to the shop and they tested it and confirmed the fuse had blown and said the package I bought came with athermostat to replace both at same time...so, I did that. Same thing the fuse has blown again. I have already put nearly $40. in parts and keep having this issue. Would it be an issue the dryer is having or is it a possibility there is a wiring issue in my apartment? It is an old apartment built I believe in the 60's...Its been remodeled but, probably same wiring. Thanx in advance for any help:confused:

More likely you have a venting problem, that is the most common cause for blowing the thermal fuse.
When you changed the fuse I am assuming that the hi-limit thermostat was also changed. Often this is a 250 degree hi-limit and a 350 degree fuse. You did not include a model number so I cannot say for sure.It should have opened before the fuse blew but sometimes heat will continue to build up from hot parts even after the heater is shut off.
Another possibility is that you have a grounded element.
The element is touching the case and therefore the thermostats do not control it.
This would explain why the fuse blew when you had a matched hi-limit.
Unplug the unit
Remove the wires from the heater and measure it, should be around 10 ohms.
Then measure from each heater connector to ground both should be infinite ohms (open). |
