Question about Roper RGS7646KQ Gas Dryer

1 Answer

I have a Roper gas dryer (RGS7646KQ2) which is not heating up to dry clothes. The drum turns and the timer works as well. It appears to be acting normally, except it is blowing cold air instead of warm air. would it be the heating element or perhaps lint build up somewhere? I have heard that lint build up may cause the dryer not to heat. is that true? Thanks. Todd Husmann

You have a bad thermostat, flame sensor, thermal fuse, gas valve solenoids, or the high limit thermostat. Below is a video to walk you thru the diagnostic testing and repair.

Roper dryer works on high heat only


DID U CHECK THE HI LIMIT AND THE CYCLING THERMOSTAT? AS WELL AS THE MOISTER SENSOR?

Dryer venting issues slow drying, fire flare ups, to hot, noise and clothes ripping etc

A lint filter that is full of lint will restrict airflow and lengthen dry times.
A blower wheel that is not firmly attached to the drive motor can slip and therefore not move air fast enough to properly dry clothes or even reduce airflow to the point where the high limit thermostat may trip and turn off the heat circuit.
In gas dryers, defective gas valve coils can create a symptom of taking too long to dry if they are intermittent. Check for proper flame ignition for the complete dry cycle to determine if this may be the cause.

The drum seals are used to prevent excess air from entering the dryer drum and act as a cushion between the drum and the front and rear bulkheads. The drum seals are made up of a felt like material. If the seal is torn or is worn then clothing can become stuck in the gap when the drum is turning. This can produce a scraping or thumping noise and the clothes can also be ripped and/or have black marks on them.
DOOR SEAL When the door is closed in gas and electric dryers the door seal helps to keep cooler air from entering the drum.

The vent tube or line itself. If it is kinked, smashed, to long, or filled, clogged with lint build up it can not only cause slow dry times but create a fire safety hazard. Try to stay away from using plastic or flimsy cellophane venting, aluminum is best!

To provide better air flow and heat dissipation try the following
Note the length of your dryer vent is a determining factor in how efficient your dryer will perform. If the total length of your pipe exceeds 25 feet then your dryer simply won't be able to perform as should, especially if your pipe runs vertically and through the roof. This is where a booster fan is sometimes needed. Booster Fans provide the extra push of air to exhaust the moisture and lint to the outside. These fans operate only when the dryer is activated, this is done by sensing the air flow through the pipe by a pressure switch mechanism or an electrical sensing relay which in turn activates the booster fan blower. I personally try to avoid adding booster fans simply because they are usually placed in a crawl space or attic and are therefore "Out of sight and out of mind." What I mean is... the unit could malfunction and you would never be aware of it. The result would be a restriction in the pipe which would cause a build up of lint at the fan. In addition, it's recommended that lint traps be placed before the fan itself which has to be cleaned out frequently. These can also easily be overlooked.

1. On gas and electric dryers that have an "Auto Dry" cycle, the cycling thermostat is often used to advance the timer as well regulate the drum temperature. Essentially, thermostat will alternately turn on the heat source or the timer motor when the temperature has been satisfied. To check this thermostat, you will have to check for power to the timer motor with a multi-meter, during a cycle. This is a live voltage test and caution should be used.

2. Some dryers will use a cool down thermostat to tumble the clothes without heat, at the end of the dry cycle. Power is routed through this thermostat to the drive motor to keep it running until the drum temperature has dropped to a specific temperature. If this thermostat fails it can cause the drum to turn indefinitely or until the door is opened. You can check the thermostat for continuity with a multi-meter. This test should only be made with the power removed from the dryer.

Lastly check the moister sensor for OHMS according to ur schematic as it must show a certain amount of ohms as per ur unit. When unit has been on short while

Heat is not always coming on in dryer. Roper dryer from Lowes


There are numerous temperature sensors on the dryer. Some are near the drum, some could be near the lint filter if it is located inside the dryer door. Try changing these first as they are an in expensive fix. It could also be the heating coils themselves. Highly unlikely it would be the dial, unless the dial was accidentally turned in the wrong direction.

Roper Electric Dryer Heats but drum won't spin


Yank the filter out the top. Remove the 2 screws in the filter housing. Use a putty knife to pop the top and then remove the screws holding the front on. NOTE: raise up on the front panel slightly so you won't damage the bottom clips. Get the front out yer way and remove the drum. Clean out the dryer and oil the rollers and idler. Use this handy ROUTING GUIDE to see how to put the belt back.

Hi I am trying to clean my drain unsder my washer. I do not know how to pull the cover off.?? It appears I need special alan wrenchs for two little screws..?? any ideas??


Though the idea of repairing a clothes dryer can be pretty intimidating, the truth is that some types of repairs are surprisingly easy. Yes, dryers appear to be built like huge, impervious metal boxes, but they are typically pretty easy to open and relatively simple to fix.


As shown at How Clothes Dryers Works, a clothes dryer has a motor that turns a big drum containing the clothes, a heat source for blowing warm air into the drum to dry the clothes, and controls for operating the motor and heat source.
Some dryers have an electric element to do the heating while others utilize a gas flame; the latter must be vented.
Clothes dryer problems generally occur because the heat source doesn't heat properly or the motor fails to turn the drum.
If a gas dryer doesn't dry properly, the first thing to check is the pilot light or igniter--it may not be lighting the burner. The second thing to check is the dryer's vent-if it is clogged with lint, the heating system won't work properly.

Pay attention to basic safety measures when working on a dryer. Always unplug the dryer, and turn off the gas supply to a gas dryer at the appliance shutoff valve.
As with most appliances, maintenance will keep your dryer purring. Clean the lint trap after every load, and clean the vent system once a year.
