No Power to Gas Valve
Kenmore 70 Gas Dryer
Took apart and checked with Ohm. Blower is running and has power (obviously) but there is no power going to the Gas Valve. What's my next step?
Thanks so much!

trace wires
you will find sensors that will open under certain conditions (usually overheat) in line as safeties. some may be manually resettable, ohm them out for continuity. if open, replace them.

Hello HandeMom. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.
The questions are:
You took what apart??? The dryer or a part?
You ohm checked what???
Is the glow ignitor working? Is it glowing?
If not it must be replaced. If it glows but the gas valve fails to open, no burner flames will be present. If this is the case, the solenoids on top of the gas valve could be defective.
The flame sensor could be defective. Depending upon specifically what the dryer was not doing and if the coil glows or does not glow, the burner lites up or does not lite up, etc depends on how I can be more specific with possible problem parts to check.
Suggestions:
Read the manufacturers online web site for product information, problem possibilities, causes and solving methods, part locations, disassembly, reassembly methods, repair procedures and instructions, pictorials and schematics, which may be available online.
An excellent source for orginal replacement parts is your local retail appliance parts store. Appliance parts dealers test and carry replacement parts for all appliances. Parts dealers are listed in the phone book.
Retail parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers if you stop in at the store. The info will help to determine the exact parts used in the model assembly line run and possible problem causes.
Tips:
I do not recommend relying solely on ohm meter tests to determine if any electrical or electronic part or parts are causing the problem. The idea is not to replace costly parts until the defective one is positively found.
The only positive proof any part is functioning correctly, is to carefully remove the part or parts you suspect to be the potential problems and have the local appliance parts store person test it or check it. Appliance parts dealers carry replacement parts for all appliances and are listed in the phone book under appliances.

Check the prior questions pertaining to dryers, within this forum, to obtain additional information. These prior postings and any or all the replies offered within them which will contain almost all the required information needed pertaining to the many potential and or possible problems with dryers like your describing.
DRYER SERVICE TIP:
It's always adviseable to clean the entire exhaust venting system every 2 years and or during any dryer maintenance and or repairs.

I took the entire dryer apart to get at the blower and gas valve.
(even the drum is removed) I checked all the electrical connentions and such with the OHM meter while the machine was running - hence I know the blower is working and has power.
The glow ignitor is not working because power isn't even going to the first connector of the gas valve hence no continuity through the whole apparatus. Checked Sears.com and they don't even have a "Selonoid" listed on their parts list for my dryer.
Since no power is even getting to the glow ignitor by via the gas valve I don't know what my next step is. I have read/printed all replys and links suggested in other subjects concerning Gas dryer.
In your opnions what could be wrong if there isn't electricity even getting to the gas valve?
Does the start button have 2 contacts? One for blower one for Gas valve? Could it be the starter button even though that IS turning the blower on?

Could you relate that into laymans language - I don't know where a sensor is nor what it looks like and also in line safties.
thanks for helping

Hello Again: HandeMom
In the back of the dryer on the exhaust vent is a part called a thermal fuse. Try a continuity test on this part. If the reading indicates no connection across it's terminals, the part is defective and must be replaced.
There are usually one or two sensors located on the fan blowers housing. Test those also. Same results, replace the one that is defective. These parts are usually round and seated in an oval shinny plated securing device. The sensor is about the size of a quarter and will have two wires attached to the terminal, one wire on each terminal.
