INTRODUCTION
The information presented in this manual applies to the 27" negative pressure dryer,
both electric and gas models.
No distinction has been made between the gas and electric models as long as the
components and/or service procedures are common to both. However, anything of a
unique nature between these models has been detailed and labeled as such in the
manual.
Since the dryer was designed to utilize the modular concept of assembly, the same
approach was taken in the preparation of this manual whenever possible.
The manual is printed in a loose format and is divided into sections relating to a general
group of components and/or service procedures. Each section is further subdivided to
describe a particular component or service procedure.
The subdividing of the subject matter plus the loose leaf form will facilitate the updating
of the manual as new or revised components are added or new models are introduced.
Each page of the manual will be identified in the lower right-hand corner, and as new or
revised pages are published, the manual can easily be updated by following the filing
instructions on the cover letter of the supplement.
This service manual is a valuable tool and care should be taken to keep it up to date by
prompt and proper filing of subsequent pages as they are used.

SAFETY NOTES
This manual is designed and intended for the experienced service technician; one who
possesses a level of mechanical and electrical knowledge commonly recognized as
acceptable in the appliance service field and who is familiar with the construction and
operation of Maytag serviced products. Maytag and/or the product manufacturer assume no liability for the use or interpretation of this service manual by any other persons.
To reduce the possibility of personal injury and/or property damage, it is necessary to
observe certain safety precautions during the servicing of electrical or gas model dryers. The following are some, but not necessarily all, of the precautions which should be
followed:
1. Disconnect electrical supply before servicing machine.
2. If electricity is required for a test; first, make any connections or adjustments
required for the test; second, reconnect the electrical supply; third, perform the
test. If additional service is required, disconnect the electrical supply before con-
tinuing.
3. On base model dryers, do not disturb a gas carrying component or connection
until the gas supply to the dryer is shut off. Following the repair, make certain all
gas connections are properly secured by testing for gas leaks with a bubble or
soap solution.
WARNING: DO NOT use a flame to test for gas leaks.
4. Never attempt to bypass or otherwise interfere with the proper operation of any
device engineered into the product.
5. Ground wires, usually green in color, should never be used as current carrying
conductors.
6. Use only authorized factory replacement parts.
7. Prior to reconnecting the electrical supply to the dryer after servicing, ensure that:
• All electrical connections within the dryer are correctly and securely attached.
• All electrical leads are properly protected from sharp edges, high temperature
components and moving parts.
16023116
SAFETY NOTES vii
• Any uninsulated current carrying metal parts have adequate spacing from
all non-current carrying metal parts.
• All electrical grounds, both internal and external to the dryer, are re-established
and securely connected.
8. Following the servicing and prior to operating the dryer, properly and securely
reassemble all panels.
