I have a Roper Model RES7745PQ0 29" Electric dryer that stopped running. I have tested all switches for continuty and have the proper voltage at the motor . Timer appears to be working, and moving but no signal to the motor when the start button is pushed. Start button stays in and pops out when I manually turn the timer. Where and what do I check next. I have the dryer on my shop table in several pieces and I am almost to the point of taking it to the scrap yard and buying a new on but feel as though I am overlooking something. Any ideas would be greatly appreciated.
Thanks:confused:

Here are your parts Replacement parts for WHIRLPOOL RES7745PQ0 29"electric Dryer | AppliancePartsPros.comHere is a wiring diagram http://www.servicematters.com/docs/wiring/Wiring%20Sheet%20-%208528190.pdf[COLOR="Blue"]I have tested all switches for continuty[/COLOR] Did you check the thermal fuse on the blower, Item7 in Section 3. I am assuming this included the Push To Start relay contacts. Did you check the timer switch 4 and the timer BU/BK contacts? [COLOR="Blue"]and have the proper voltage at the motor . Timer appears to be working, and moving but no signal to the motor when the start button is pushed.[/COLOR] Do not understand the above. You say you have voltage and then say you do not get a signal which I interpret that you do not have the correct voltage. If you have 120 volts across the motor it should run, if not it is toast. Check it's windings for continuity. |

denman,
thanks for the schematic, Going down your checklist this morning I removed the timercompletely to check the timer switch 4 as you sugessted. Once I removed it I heard something rattling inside it. I put my meter on T & W terminals, which if I understand the schematic correctly should be a closed contact throughout a majority of the timer positions, it was not showing any continuity. I removed the metal plate from the back of the timer switch and out fell a little round piece. After futher inspection it fell off of the end of the W contact. I think there is here my problem is!! Thanks for thevery helpful information and I will let you know how it turns out after I replace the timer.
Regards,
CSnyder
