What does ERR-1 message indicate?

This indicates it is the High Limit Thermostat, which isn't a fuse. Most dryers have three heat related components. They usually trip because of bad airflow, check the hose at the back and the vent in the wall. This is the time that birds make nests in them! Also wash the lint filter with dish soap and a brush. Part No. 33 here

The error code of E65 is a high limit thermostat trip . For Electric Model, check Inlet Thermal Limiter for continuity. If Thermal Limiter is open, check for evidence of high temperature event and any resulting damage. If no further damage is evident, replace Thermal Limiter.

Frigidaire dryer still codes E65 after an E64. Replaced heater ...

I expect it has 4" duct exhausting to outside? It's possibly restricted with lint, either at the louvered opening, or in the pipe itself. Spiral plastic vent is particularly restrictive and captures more lint than smooth sheet metal pipe. A restricted exhaust/limited air flow will likely trigger a filter message.

Is this happening on automatic dry cycle or timed drying?
It sounds like your moisture sensor is "confused" and shutting down heat prematurely.This part can be replaced.

Also double check your exhaust vent for blockages or standing water or sagging or open pipe

Also , your heater element may be shutting on or off prematurely. Could be a high limit thermostat problem. Or there is obstuction causing over heat

hope this helps

There is a high limit switch (looks like a button with two wires hooked to it) on the bottom of the vent frame. When the vent fills up with lent at the bottom it gets hot. For safety, this limit switch will turn heat off. Remove the vent frame and clean it out and check the continuity of the switch. Also, make sure both heater elements are working properly.

If the heating element is fine check the limits:


Your fuse is ok because the dryer runs. So one of the heater limits is probably blown.
The 2 above limits fit a standard WP dryer. Yours might take a diff part number depending on the model. If all limits are fine, yall could have a bad breaker, a bad temp control or a bad timer.

Hello,

Welcome to FixYa.

Based on your description "dryer runs,but no heat" I`d direct you to first check the hi-temp cut out at the back...if you haven`t already.

It will look like this...



If you push this to reset and the unit works, great. I would keep an eye on it though since the hi-limit typically trips for a reason such as a plugged lint filter, plugged vent ot partially plugged or the heater itself is plugged up with lint.

Take the lint filter and clean it under some warm water and soap as they do become plugged with wax over time due to fabric softener and static sheets.

If it doesn`t heat after-wards or it`s not tripped, you`ll need to investigate for a faulty heater element.

This is quite involved, so we`ll cross that bridge when you get there...if necessary.

Keep me posted on your progress or what you find.

Good luck.

Regards,

Macmarkus :)

Remove the exhaust vent tubing and thoroughly clean it. The best way is to take it apart piece by piece if it is made with sheet metal. If its the cheap accordian stretch tube throw it away and get the right tubing for it. Lint catches in the spiral folds and collects very rapidly causing to clog up. When it does the moister sensor detects the clog for the heat will not vent through the exhaust tubing. When that happens the sensor shuts down the heating process. If your vents are clean and clear the sensor is at fault so replacing that will be your task

What I do is see if their could be an obvious reason for the dryer to quit heating. I determine how old the dryer is and ask if the heating element has been replaced and when, those sorts of questions then that give me an idea. I make it a point to clean and oil any dryer I work o. They all are going to have lint buildup in them and this lint is the main cause of heat failure. A small piece of lint gets on the heating element and causes a hot spot. The hot spot burns through interrupting the circuit
I unplug the machine and remove the rear cover. I 1. Hi Limit (small limit upper right hand side of this pic) the most frequent problem if dryer RUNS but no heat AND you have
checked the element and found it to be good. 2. Heater assembly. 7. Control thermostat(s). 5. Fuse(350F), if blown(open) the dryer will NOT run. 4. Heater element
(if you do not have a meter remove and inspect this heater coil for breaks). I remove the lint chute(that the thing the filter lives in) and I wash that out because it gets clogged over time. I check the heater and limits for continuity. Then I remove the front panel and drum. Completely vacuum out the dryer and oil the rollers.
If this is a gas dryer you want to see if power is going to the gas assembly
If this fuse is blown on a gas dryer the dryer will run but the heat will not, If the dryer heats a little but quits then these coils are getting hot and intermittentif your igniter is blown or your sensor is openthere won't be no heat.

Check the fuse on the blower housing.
To get to the heating element on most of these dryers you remove the back dust cover: 1.

i have replaced TH2 in my dle0322 about 6 times now. It never lasts more than a month. What could be causing this?
